Aside from the added support for PowerPlay wireless charging and Omron switches that are now rated for 50 Million clicks, along with a change to a more pure black color scheme, the G903 LightSpeed Wireless is the same exact mouse as the G900 Chaos Spectrum that we reviewed back in July. The G903 LightSpeed does weigh 3 grams more than the G900, perhaps due to internal circuitry added for PowerPlay compatibility. Featuring a fairly lightweight (110G), ambidextrous design that looks like the Batmobile, the G903 LightSpeed Wireless is a great looking wireless mouse that offers amazing wireless performance that is indiscernible from a wired connection in my evaluations.
The G903 comes with an illustrated quick start manual that explains how to install the mouse in easy to follow, simple steps. A wireless USB LightSpeed nano receiver with an extension to place it on your desktop for optimal connection is also included. There are also additional buttons to add to the mouse, which we’ll get into shortly. Also included is a 10G weight for customization. Not pictured is the USB 3.0 cable, which is the exact same type we saw included with the PowerPlay mat, but with a less bulky PC-side connector. If you use PowerPlay with the G903, you won’t likely need to use this USB cable, as it is used for charging the mouse and updating firmware.
Looking at the G903 from the top, it resembles the Batmobile, with sleek curves and an ambidextrous shape that flows in a very natural way. You can tell that Logitech put lots of time into the design and aesthetic of the G900 and that all translates into the G903. The blank on the right side of the mouse can actually be removed to allow for two additional buttons to be added, or you can even remove the buttons on the left side for a no-side-button mode. The G903 allows for a nice bit of customization without being gimmicky in its attempt. The left and right buttons of the G903 LightSpeed, individual and separate from the rest of the mouse, offer the best tactile feel of any mouse I’ve ever tested, with a crisp, satisfying click and immediate bounce back. These amazing buttons are spring-tensioned and the 50-Million Click Omron switches that Logitech employs on the mouse are as good as it gets. These feel and respond exactly like the Omron switches in the G900 Chaos Spectrum and I can barely tell any difference between them, though the G903 feels like it may have a slightly softer click than the G900. Either way, I can’t tell a difference between the G900 and G903 when I am using either mouse. These Omron 50-Million click switches, thanks in part to the way Logitech has implemented them with the buttons of the G903, are quite responsive. Getting used to the G903 might lead to some unfortunate false-clicks if you’ve gotten use to a mouse with unresponsive buttons that require a bit of pressure to activate.
The G903 scroll wheel allows for either precise, ratcheted scrolling, or you can enable the infinite scroll, depending on what you’re doing. The scroll wheel allows for horizontal clicks, as well. This is one of the best scroll wheels in the industry, with a great, solid feel and very tactile, responsive clicks. The scroll wheel side clicks are assignable in LGS and can I’ve found that they come in handy as chat toggles or media controls.
The side buttons on the G903 feel great, with a nice, responsive click. The button placement works well, as it allows room for the thumb to rest below when you don’t intend to hit the buttons. The rubberized side grips on the G903 have a great feel, with just enough give to grip, but not give way. The indented lines that run up the mouse do a great job of holding the thumb in place and letting you grip the mouse without being uncomfortable.
Logitech has placed several mouse feet on the G903, which allow it to glide smoothly over surfaces. These feet have a nice, smooth coating on them and flow very well. The mouse feet sit within indents, so if they are replaced, lining them up won’t be an issue. There is a sliding switch for power, which has a nice tactile click to it and is implemented in a way which makes accidentally switching the mouse off during use nearly impossible. The button between the sensor area and the power slide allows you to switch between user profiles, for on the fly changes to more than just DPI.
I think the G903 is balanced very well with the sensor placed almost in the center of the mouse, which lends to excellent balance and control of the mouse. The weight does add some weight to the rear, which may give more control. The PowerCore module of the PowerPlay weighs 3 grams and this weight can’t be used in conjunction with it.
There is a Logitech logo towards the rear middle section of the G903. This logo is RGB can be adjusted to a variety of settings in the LGS software, or turned off. Turning off the RGB lighting will net you more battery life for when you’re on the go with your laptop and don’t have access to the PowerPlay charging system.
The G903 continues the tradition of the G903 Chaos Spectrum. The G903 looks like the Batmobile and has amazing main buttons and the best scroll wheel around. The wireless technology is the best in the industry and the mouse feels great in my hand. Logitech really implemented the modular button design well, allowing the G903 to be tuned for left-handed use by switching the thumb button location. For users who want to go all out, the ability to put buttons on each side of the mouse is unique, but to be honest, it makes things a bit awkward, as I hit the right buttons a LOT when I tested things out, because I’d put pressure on that side of the mouse when moving it.
The G903 is the best wireless gaming mouse out there and its implementation with the Logitech Gaming Software is excellent, but it comes in at a $149 price point, meaning it will be off limits to many gamers. Let’s take a look at the less expensive G703 LightSpeed wireless mouse, next.
