Logitech G603 and G613 LightSpeed Wireless Peripherals

LegitReviews recently had the opportunity to review the Logitech G703 LightSpeed Wireless Gaming mouse, along with the new PowerPlay Wireless Charging System, with both earning some awards along the way. The G703 LightSpeed has an amazingly comfortable shape for right handed users, along with very responsive Omron switches for the main buttons and of course, Logitech LightSpeed wireless technology, which I've found offers wireless performance that is indiscernible from wired performance. Unfortunately, the G703 LightSpeed only offers about two days of battery life under normal usage when RGB lighting is being used, unless you invest in the $100 PowerPlay system, which brings the cost of entry to $200. Another barrier is that the G703 LightSpeed comes in at a $100 MSRP, which will put it out of budget for many users. Fortunately, as Logitech was developing the high end G703 and G903 LightSpeed mice alongside PowerPlay, a more economical wireless mouse was being devised for the masses, along with a wireless keyboard that would offer 1 ms response time and mechanical keys for the first time, ever. Today, LegitReviews has the opportunity to share the results of this development, the G603 LightSpeed Wireless Gaming Mouse ($69.99 shipped) and its companion, the G613 LightSpeed Wireless Gaming Keyboard ($149.99 MSRP). https://www.youtube.com/watch?v=KO_xwwcO8PM In order to bring users a wireless mouse with acceptable battery life while still delivering performance that would be suitable for competitive gaming, Logitech had to discover a Hero. We're not talking comic books or sandwiches here, either. In development at Logitech for over three years, the Hero optical sensor is up to ten times more power-efficient than the Pixart PMW3366 that is currently being employed in Logitech's top of the line gaming mice, while offering similar tracking performance across the entire DPI range. The Pixart PMW3366 sensor is widely considered one of the best optical sensors in the world, offering zero acceleration and smoothing, so Logitech has a lot to live up with their Hero sensor. With other mouse manufacturers relying on Pixart and others for their sensors, Logitech is taking a bold step by developing their own sensor, but they are one of the few companies with the R&D to pull it off. I've found that their other in-house technologies like LightSpeed and PowerPlay have been excellent, so I have high hopes for the Hero sensor. Logitech Hero Sensor - Optimizing Efficiency and Performance Promising performance on par with the best optical sensors on the market, but with much greater power efficiency, the Logitech Hero sensor does frame-rate processing based on the use of the mouse. If the mouse is idle, the frame-rate processing of the Hero can be turned off to allow for as little power draw possible from the mouse. When the mouse is in use, the intelligent processing of the Hero sensor is able to adjust frame rate processing to an acceptable level in order to optimize power draw. The Hero is capable of doing all of this on the fly, while maintaining full accuracy across the entire DPI range, with zero filtering, smoothing or acceleration taking place. Essentially, the Logitech Hero offers similar performance as the Pixart PMW3366, but with next level power management that draws much less juice in idle situations. Finally, the Hero sensor offers some weight savings over the PMW3366 and other current Pixart sensors, a great development for wireless mice, which struggle to keep weight low due to the battery and wireless circuitry that they possess.Logitech G603 LightSpeed Wireless Gaming MouseThe G603 LightSpeed Wireless Gaming Mouse (PN# 910-005099) is based around the same design as the G703 LightSpeed ($93.82) and G403 Wireless ($89.99). The decision for Logitech to expand the style of the G403/G703 Wireless to the G603 LightSpeed was a wise one, as it is a very comfortable, practical design that has received excellent consumer and reviewer feedback. The G603 LightSpeed Wireless Gaming Mouse is capable of running at a 1 ms report rate for up to 500 hours on just two AA batteries, which are included. Users who are interested in a G703 LightSpeed but can't spend the $100 asking price, or who want longer battery life than the two days provided by the G703, will certainly be interested in the $69.99 G603 LightSpeed, as it offers the same shape, similar Omron main button switches and of course, LightSpeed wireless technology. Logitech G613 LightSpeed Wireless Gaming Keyboard The Logitech G613 LightSpeed Wireless Mechanical Gaming Keyboard (PN#920-008386) is a full sized unit in two shades of grey, featuring Romer-G mechanical switches, six programmable dedicated macro buttons and a built-in wrist rest. Designed to go alongside the G603 LightSpeed Wireless Gaming mouse, but capable of running on its own, the G613 LightSpeed operates at a 1MS response rate and can last for up to 18 months on just two AA batteries. There is currently a lack of wireless mechanical gaming keyboards that can be used in the competitive arena, with even solid, well-made keyboards like the Filco Majestouch Convertible 2 being limited to a high latency, inconsistent Bluetooth signal that has a variable response rate that is above 10 ms. The Logitech G613 LightSpeed fills a void for users who want a mechanical wireless keyboard with a consistent enough signal to rely on when playing games and doing other critical tasks. In addition to running on the low-latency Logitech LightSpeed signal, the G613 can switched to run in Bluetooth mode for instant compatibility with a variety of devices. Switching between two systems on the fly, say an HTPC and a gaming PC, is totally possible with the G613 LightSpeed. Logitech G603 and G613 Wireless Combo Let's take a closer look at the G603 LightSpeed Wireless mouse and included accessories, next. We'll follow that up with a closer look at the G613 LightSpeed Wireless Gaming Keyboard.

Logitech G603 LightSpeed Wireless Gaming Mouse

Logitech packages the G603 LightSpeed Wireless gaming mouse in a grey box with blue foiled "G603" text running vertically next to a top angled graphic of the mouse. The graphic of the mouse and blue foil "G603" stand out nicely from the matte grey background. The G603 LightSpeed wireless box follows a professional aesthetic, lacking crazy fonts or logos to try and attract gamers, but instead focusing on the mouse itself.

  Logitech G603 LightSpeed Wireless Gaming Mouse - Retail Box (Rear) The Hero Sensor, LightSpeed support, 500 hours of battery life and the Bluetooth support that allows the G603 to be used with more than one PC with the press of a button, are all explained on the rear of the G603 LightSpeed Wireless box. Logitech did a great job of listing the features in a clear fashion that a customer picking up the mouse off the shelf will find easy to understand without being overwhelmed. After looking at and reading the packaging for the G603 LightSpeed Wireless, you would expect it to be a no-nonsense, high quality gaming mouse with excellent battery life and solid wireless performance, which is exactly how Logitech is marketing this mouse. Logitech G603 LightSpeed - Clamshell Logitech packages the G603 LightSpeed into a two piece clamshell within the outer box, with the USB extension cable, LightSpeed USB Nano receiver and 2x AA batteries all set into specially tooled sections of the lower clamshell. The upper clamshell has been removed in this picture so that the included components can be seen more clearly. Even though the presentation isn't anything to write home about, Logitech does a good job of properly packaging the G603 LightSpeed and accompanying accessories to protect them from damage and they can be easily accessed by customers when they first open the box. Logitech G603 LightSpeed - Top View The shape of the G603 LightSpeed Wireless is very familiar to me, as it uses the same shape and button layout as the G703 LightSpeed Wireless, with just a few tweaks here and there. The G603 LightSpeed is ideal for medium to large hands, with just under five inches of length, 2.68 inches of width and a little over one and a half inches of lift. The G603 LightSpeed has plastic construction throughout the exterior of the unit, with a grey top and mouse button area and black accents lining the sides and scroll wheel area. Gone is the rubberized side area we found on the G403 Wireless and G703 LightSpeed, unfortunately. All of the plastic on the G603 LightSpeed Wireless mouse feels high quality, though, with the side and main buttons offering satisfying clicks. The top cover of the G603 LightSpeed contains the spring and swivel mechanism for the buttons, similar to the design seen on their other G-series mice. Even though it cannot feature the independent button design of the the G903 or G703 due to featuring a single-piece top, the G603 has very solid manufacturing tolerances and the swivel mechanism of these buttons is very well made. Logitech G603 LightSpeed - Scroll Wheel The scroll wheel on the G603 LightSpeed Wireless has an assignable click and is very similar to the scroll wheel on the G703 LightSpeed, offering a satisfying ratchet scroll that is smooth and responsive, never causing any overshoot. The scroll wheel click on the G603 LightSpeed is a little bit softer and easier to press than the one the G703, so I actually like the G603 scroll wheel just a little bit more. Logitech G603 LightSpeed - Side Buttons The side button area of the G603 LightSpeed has a plastic grip area that is comfortable to hold and I didn't have any issues with the mouse slipping, though the plastic material of the G603 doesn't provide the solid, reassuring grip of the rubberized texture found on the G703 LightSpeed. Given the cost difference and weight considerations of the G603 LightSpeed, I'd say the use of plastic grips instead of the rubberized ones found in the more expensive mice is a fair trade off and one that doesn't take away much from the experience in day to day use. Logitech G603 LightSpeed - Side View The G603 LightSpeed weighs in at 112.3 grams with a single AA battery installed, or 135.7 grams with two AA batteries installed. While not in the realm of competitive gaming mice like the Logitech G Pro (83G), the Logitech G603 Wireless weighs just 89 grams on its own, so the AA batteries are really making up a lot of the bulk here, adding about 23-25 grams of weight, each. Since the G603 LightSpeed doesn't offer better performance with two AA batteries installed, only longer battery life, it may make sense for many users to run just a single AA battery for the weight savings. The Razer DeathAdder Elite, an extremely popular wired gaming mouse with a similar form to the G603, weighs in at 105 grams, so the weight factor of the G603 LightSpeed with a single battery installed is pretty impressive. Logitech G603 - Easy Top Removal Removing the top cover of the G603 LightSpeed is really simple. On the bottom rear of the mouse, there is a little area specifically for your finger to easily pop up the cover. Logitech G603 LightSpeed w/Batteries Installed Underneath the plastic top of the G603 is the battery compartment and a holder for the LightSpeed wireless transmitter, which is unique to the G603 mouse that it ships with. This is a very well thought out design from Logitech, with the batteries able to be easily installed and removed, while giving the user an easy to access location for their LightSpeed transmitter, so that they can take their mouse with them and not have to worry about losing the proprietary transmitter. Logitech G603 LightSpeed - Magnets The plastic top of the G603 LightSpeed is held on with nicely spaced out magnets and fits very securely, with no issues of it rattling or slipping when in use. Logitech has done a great job of keeping everything really clean and tight with the manufacturing here, as all of the lines are perfect and the top fits perfectly with the base of the mouse. Logitech G603 w/Omron Switches With the top cover of the G603 LightSpeed removed, we can also get a good look at the Omron main button switches. These switches, tested by Omron to last for 20 Million clicks, offer a very satisfying, crisp response and have been used in various Logitech G series mice, including the original G403. Due to the G603 having a single body design, rather than independent buttons, I thought the clicks wouldn't be quite as consistent as they are on the G703, but the difference is only very slight in the favor of the G703; the buttons on the G603 LightSpeed offer satisfying, responsive, consistent clicks nearly on par with those offered by the more expensive G703 LightSpeed.Logitech G603 - Bottom Area The feet on the bottom of the G603 LightSpeed have excellent coverage, curving around the top and bottom area of the mouse on both ends. These are the same excellent mouse PTFE Teflon mouse feet that you will find on the G403 Wireless and G703 LightSpeed, allowing for excellent gliding and control on either cloth or hard surface mouse pads. In my experience, these mouse feet hold up well on cloth mouse pads, with my G403 Wireless showing minimal, normal signs of wear after about a year of use. Given the popularity of the G403 Wireless/G703 LightSpeed mice, aftermarket mouse feet using a specially treated PTFE Teflon that is much slicker than stock and designed for competitive use are available from Hotline Games. Logitech G603 - Power Switch On the bottom of the G603 LightSpeed, there is a three position switch that is used to set the report rate to either Hi (1 ms) or Lo (8 ms), or turn the mouse off. This switch has a notch in it and is easy to use, with a nice tactile click between each setting. On the other side of the report rate/power switch is a button that will let you toggle between the LightSpeed wireless connection and Bluetooth. This can come in really handy if you have a gaming PC and a laptop that you want to share the G603 LightSpeed between. Instead of having to remove the LightSpeed receiver from your gaming PC, you can just use the Bluetooth connection of your laptop with the G603 LightSpeed. While Bluetooth can't offer the stable 1 ms response time of LightSpeed, it is still capable of a 7.5-11.25 ms wireless response rate with the G603 LightSpeed. Logitech G603 - Side Area Overall, the G603 LightSpeed Wireless Gaming mouse has an excellent build quality paired with a proven shape. Using the G603 LightSpeed and then switching over to a G703 LightSpeed, I could barely tell a difference between the two mice, with the only obvious tell being the weight difference and the feeling of the plastic sides of the G603 LightSpeed versus the rubberized texture of the G703 LightSpeed. The wireless performance between the G603 LightSpeed and the more expensive G703 LightSpeed and G903 LightSpeed mice was indiscernible. With the LightSpeed transmitter capable of operating on USB 2.0/3.0 ports and Bluetooth support also present, the G603 LightSpeed will be ready to go on a variety of systems. When it comes to reliable wireless performance, if it says LightSpeed on it, in my experience, it's solid.
Let's take a look at the G613 LightSpeed Wireless Mechanical Keyboard, next.

Logitech G613 LightSpeed Wireless Gaming Keyboard

The G613 LightSpeed Wireless Gaming Keyboard is packaged in a box that matches the colorway and design of the G603 LightSpeed Wireless. Grey with blue foil accents are in use and the box has a very professional, clean look that might appeal more to an office user than a gamer, but that is just fine. Logitech G613 Retail Box

Logitech G613 Box Rear The G613 LightSpeed Wireless comes with a 2-Year warranty against manufacturers defects, which is a decent warranty for a keyboard, as we've seen many brands that only offer one year of support on their keyboards. Logitech G613 - Open Box Logitech ships the G613 well-packaged, surrounded nicely and protected from potential shipping damage. Included in the box are a user guide, USB extension cable and LightSpeed Nano USB transmitter, which pairs with the specific G613 LightSpeed Wireless Gaming keyboard that it comes with, so do not lose it. Unfortunately, the LightSpeed Nano USB transmitters are not unifying like we've seen on other Logitech products, so you will need to install transmitters for both the G603 and G613 if they are run on the same machine. My sources at Logitech have said that it is possible that future LightSpeed transmitters will allow for more than one connection and that it is something Logitech is looking into, but for now, LightSpeed is limited to just one connection per transmitter. Logitech G613 Cell Phone Holder Logitech also includes a cell-phone/tablet stand with the G613 LightSpeed. This can come in useful when you want to keep a cell phone or tablet on your desktop to pair with the G613 LightSpeed, giving you an option that beats the heck out of the on screen keyboard. The cell-phone/tablet stand is definitely a nice value add to include with the G613, though I actually ended up using it as stand for my NVIDIA Shield TV remote, which is very easy to misplace, since I already have a Qi charger for my phone that stands it up vertically. The Logitech G613 - US 108 Key Layout The G613 LightSpeed has a 108-Key US layout with a solid grey frame and flat bezels across the top and sides of the unit. Coming in at 3.2 pounds with batteries installed, the G613 is not a lightweight accessory, by any means, which may limit its appeal to those looking at it from a portability standpoint. There is a non-removable built-in wrist rest in a different shade of grey. There is a steel backplate underneath the keys, which lends to the rigidity and durability of the G613. The frame and wrist rest of the G613 LightSpeed have excellent build quality, offering minimal flex and giving peace of mind that this keyboard is going to be able to survive over the long haul. Logitech G613 - Romer G switch Logitech has equipped the G613 LightSpeed with their Romer-G mechanical switches on every key, except for the media buttons. The Romer-G switch was developed by Logitech in a partnership with Omron and they offer a slight tactile bump with an actuation point of 1.5 mm, which is currently only bested by the non-tactile Cherry MX Rapidfire, as far as I know. The Romer-G switch was built to allow for an LED to sit in the center stem for a uniform lighting, but the G613 omits lighting in favor of longer battery life, so we don't see that feature used here. Logitech and Omron rate the Romer-G switch for 70 Million clicks and I've found them to be an excellent switch once you get used to the way they feel. G613 Macro Buttons - Top View Six programmable macro keys line the left side of the G613 LightSpeed and they feature the same Romer-G switches as the rest of the keyboard to allow for consistent, responsive presses. These macro keys are spaced in groups of two and are easy to reach with your left pinky finger when you are typing, so they can allow for some real functionality when in-game. You can program these buttons to do multiple key presses at the same time, so if you want to do some crouch-jump action in PUBG without having to do odd keybinds, it is totally possible with the G613 LightSpeed and accompanying Logitech Gaming Software. Logitech G613 - Media Keys The upper right corner of the G613 LightSpeed features a full set of media controls, including a volume rocker and mute button. The stop button is square to help differentiate from the others, but with so little buttons present, we think just leaving them all the same shape for a cleaner aesthetic would have been the right design choice. The media control buttons all have a solid, consistent feel and were responsive to my presses. Logitech G613 Toggle Switches To the left of the media keys there are buttons to toggle between Bluetooth and LightSpeed operation, in addition to a Game Mode switch, which disables the Windows key (or any other key you program in LGS) to prevent it from being pressed during the heat of battle and accidentally tabbing out of your game. These buttons are in a clever, easy to reach area that remains out of the way of potential accidental presses. When you press either button, it will light up for about four seconds to let you know which wireless mode has been activated: LightSpeed or Bluetooth. To the left of the toggle buttons, we find a CAPS LOCK and battery life indicator, which will show up green during use and flash as the battery drains and nears the end of its useful life. G613 -Textured bottom with rubber feet The bottom of the G613 LightSpeed has a slotted plastic along with three rubber feet that cover the entire bottom of the wrist rest area that helps it grip very well to whatever surface it is on. On the top portion of the bottom of the G613 LightSpeed there is a battery door that can easily be removed to install new AA batteries. The wrist rest is built into the keyboard, which definitely doesn't help the portability factor. Logitech G613 - Keyboard Feet Adjustable feet on the bottom of the G613 LightSpeed allow for optimal height adjustment. I found the keyboard to be perfectly comfortable in its stock, flat configuration, but different users will have varying preferences in this regard, so it is nice to see some level of height adjustment on the G613. These height adjustment feet are stable and didn't have any issues staying in place and keeping the keyboard stable under aggressive use scenarios.Logitech G613 - Battery Area The battery area of the G613 LightSpeed easily opens and has an area where you can store your LightSpeed Nano USB receiver. When the G613 LightSpeed ships, the batteries are already installed and the receiver is in this location. Logitech gives users instructions on how to remove the cover and activate the keyboard. Logitech G613 KeyCaps Overall, the G613 LightSpeed is built to last, with solid build quality found throughout the keyboard. The keyboard grips well on various surfaces and has a great feeling when typing, without any plate flex or other notable build issues present. The included wrist rest works well, keeping your hands more level with the typing surface, as wrist wrests are intended to do. While the use of UV coated key caps instead of ABS doubleshot key caps was a bit of a letdown, I was thoroughly impressed by the other aspects of the G613. The LightSpeed wireless connection of the G613 worked well, even if I got several feet from the PC. Trotting the keyboard fifteen to twenty feet away still allowed it to work, so the G613 LightSpeed has a decent amount of range. I found myself using the Logitech G613 LightSpeed quite a bit since it arrived here for testing and it's taken up a place as a mainstay in my desktop setup, though I am patiently awaiting a wireless version of the Logitech G Pro keyboard to come along and sweep me off of my feet. Let's take a look at the Logitech Gaming Software and how it interacts with the G603 and G613.

Logitech G603 and G613 - Logitech Gaming Software

The current version of Logitech Gaming Software is version 8.96.81. The total size of the LGS download is about 118MB and it is compatible with Windows 7 and up. In order to get advanced functionality out of your Logitech G603 and G613, such as setting custom DPI for the mouse and programming keyboard macros, you will need to download and install the LGS. In my experience, the current version of LGS works well and I haven't experienced issues with it on Windows 10 64-Bit across a variety of Logitech G-Series products, including headsets, keyboards, mice and webcams. G603 - LGS Main Screen Logitech Gaming Software is able to detect your hardware and provide a graphic representation of the Logitech product(s) you are using, as you see here with the main screen for the G603 LightSpeed. I really like this touch, as it makes configuring different Logitech devices really simple, as each product stands out in LGS and has its own section with dedicated controls. Logitech G603 - LGS The LGS lets you set five different DPI levels on the G603 LightSpeed, in addition to providing the current battery life. Polling rate can also be set in LGS, though there is also a physical switch on the bottom of the G603 that will let you manually change the mouse to a 8 ms (125 HZ) polling rate. Unlike most of the other Logitech G products, the G603 and G613 don't feature any lighting, so the LGS sections for these products aren't as expansive as I am used to. LGS gives full product control over the G603, with the ability to update firmware and program all of the buttons. Logitech G603 vs G903: Different Battery Readings The main difference I could see between the G603/G613 and the G-Series products with built-in batteries is that the products with proprietary, built-in batteries provide an actual percentage of battery life left, whereas the G603 and G613 give more of an approximation of battery life that is represented by five bars within the battery. For example, the in the picture above we can see that the G903 gives us an approximate amount of time remaining in the battery. The Logitech G903 can display a percentage of the battery left, G603 can't I can also click the "Battery" tab in LGS for an exact percentage of battery life remaining in the G903 and G703. With the G603, this is not possible. The battery detection in LGS works with the G603 and G613 to alert you when the battery is getting low and you will have plenty of time to replace your batteries before they bite the dust. Logitech G613 LightSpeed LGS Main Section The main section of LGS for the G613 LightSpeed Wireless Gaming Keyboard gives a full profile view of the keyboard and gives immediate access to programming the macro keys. LGS G613 Setting - FW Update and Poll Rate Under the settings tab for the G613 LightSpeed, you can set the polling rate and check to see if you are running the latest firmware, which our unit shipped with. The G603, like other LightSpeed products, is able to do firmware updates over the wireless LightSpeed USB Nano connection. G613 - Macro Section The macro programming section is pretty expansive and you can program any variety of macros to the keys. Custom strings, media launch, game actions and more can be programmed in the LGS macro section. LGS G613 Game Key Section In the Game Key section of LGS for the G613 LightSpeed, you can set which keys are disabled when you switch on the "Game" tab on the top right front of the keyboard. This feature comes in very handy. The LGS allows full control over both the G603 and G613 and it was completely stable throughout my testing. Assigning macros to the G613 LightSpeed was as easy as could be and the simple layout of LGS should be easy for most consumers to pick up and get right into. We'll sum up our overall feelings on the G603 LightSpeed Wireless Gaming Mouse and G613 LightSpeed Wireless Gaming Keyboard on the next page.

Logitech G603 and G613 - Final Thoughts

Logitech G - Play Without Limits Logitech has gone a great job of bringing two new wireless gaming peripherals to market with the G603 LightSpeed Wireless Gaming Mouse and G613 LightSpeed Wireless Gaming Keyboard. With the G603 LightSpeed Wireless, we have a mouse that performs and behaves very similarly to the $93.82 G703 LightSpeed Wireless. We found the build quality of the G603 LightSpeed to be superb, with the mouse buttons offering crisp, responsive clicks that were identical to those we experienced on the G703 LightSpeed, with perhaps just a bit less crispness due to the G603 not having independent buttons. Logitech did a great job of allowing for a bit of weight customization with the G603 LightSpeed, as removing one battery won't hurt performance and will allow for more nimble movement. AA batteries add a lot of weight and don't allow for perfect balance when one is removed, but the G603 does a good job of balancing itself, despite the limit presented by AA batteries. Gaming performance was excellent with the G603 LightSpeed, as we never experienced any drop outs or erratic tracking, even under the most extreme conditions. Logitech Hero Sensor Tracking performance on the G603 LightSpeed felt exactly the same as it does on the G703 and the Hero sensor behaves and performs exactly like the Pixart 3366 I've become used to, while drawing less power. It was impossible to get the Hero sensor to spin out or behave erratically, even if I tried. Kudos to Logitech for developing a relevant new sensor for wireless mice. I can't wait to see Hero implemented in future Logitech products. I can actually see Hero being really useful on a wireless version of the G Pro mouse, offering weight reduction and battery savings which can allow Logitech to use a lighter, lower capacity battery. Maybe I just want a wireless G Pro really bad and keep fathoming ways for it to be possible, but I am sure Logitech is way ahead of me on these things. The scenario may arise where you are running low on batteries, or perhaps another device needs a set of AA batteries and the only ones you have left are in your G603 or G613 LightSpeed. The inability to run either device in wired mode becomes a bit of a nuisance, as you will need to source more AA batteries before the keyboard or mouse can be used. On the mouse, omitting the USB interface allows for weight savings, so I understand the omission there. Perhaps Logitech could have included a cover for the G613 and included a stealth USB port, though? This really isn't a huge issue, since the batteries on the G603 and G613 LightSpeed last for so long, but it is an issue I can foresee having down the road. Logitech G613 - Stock Photo How does LightSpeed technology transfer over to keyboards? Very well. If you want a wireless gaming keyboard that is reliable enough to play competitive FPS with, the Logitech G613 is your only choice, in my eyes. None of my other wireless keyboards offer the low latency, reliable functionality of the Logitech G613 LightSpeed Wireless. I have a Filco Convertible that retails for $184.72 shipped and it has noticeable lag when typing from idle and I can tell the difference in response time between it and my G613. We're not talking a slight difference, Bluetooth just can't offer the low latency and reliability that the proprietary Logitech LightSpeed connection can. For the first time ever, I have a wireless keyboard and mouse combination that won't hold me back when playing competitive FPS. The thing is, how many people really are going to take advantage of a wireless mechanical keyboard like the G613 to the point where it makes sense purchasing it over another excellent offering, like the Logitech G810 or G Pro? I think it may have been an easier sell on this go around to bring out a TKL wireless keyboard, as that form factor makes more sense, but Logitech starting with the G613 and working from there makes perfect sense, as the G613 is a great overall unit and a safe way to introduce LightSpeed wireless to the keyboard industry. Logitech has done a great job of implementing the Romer-G switches on the G613, with proper spacing and UV coated key caps that feel good to type on, but also leave a bit to be desired. While the UV coated key caps Logitech includes with the G613 LightSpeed Wireless are decent, on an otherwise amazing product with solid build quality, they do stand out as a shortcoming, as other manufacturers are including long-lasting doubleshot ABS keycaps with their keyboards. I am also not a huge fan with how the font looks on the keys, as some didn't seem to be perfectly centered, misaligned with the UV coating. The G613 still looks great and the key caps feel fine to type on, but when you've got a diamond, you have to check it for flaws. Logitech explained that their key cap choice as having to do with worldwide logistics, but in the end, I don't think consumers care about a manufacturers logistics as much as they do getting the best possible product for their money. Logitech already has a tough time with mechanical keyboard enthusiasts because the Romer-G switch has no aftermarket key cap support, so this shortcoming stands out to the keyboard enthusiast in me. Both the G603 and G613 LightSpeed are excellent, well-built products that are worthy of your purchase if you are looking to invest in wireless gaming peripherals. The days of wireless peripherals that can't keep up with competitive gamers are long gone; Logitech LightSpeed is excellent technology and it has been implemented perfectly in both the G603 and G613. PC gamers who don't even care that much about wireless functionality, but who appreciate peripherals with a more simple, laid back aesthetic may even find themselves interested in the G603 and G613 LightSpeed, as both offer solid features for gamers while looking at home in an office setting. Instead of crazy RGB lights, we get extremely long battery life over a wireless connection with a clean, simple aesthetic. I can dig that trade off, personally. Some might not be down to trade their tricked out keyboards with lighting for peripherals like the G603 and G613 LightSpeed and I totally understand. Having a PC is all about tailoring it your personal use, so the more choice consumers have in quality PC peripherals, the better. While I think that $149 is an okay price for the G613 LightSpeed Wireless Gaming Keyboard and what it offers, the $69.99 shipped G603 LightSpeed Wireless Gaming Mouse stands out as a great value, as it offers the new Logitech Hero sensor, Omron main button switches and excellent build quality that compares well with any mouse in its price range, wired or wireless.
