The Func MS-3 is a big and heavy mouse with dimensions of 4.99 x 3.97 x 1.69 in LxWxH (126.92 x 100.69 x 42.38 mm) and a weight of 4.5 ounces (127g / 0.28lbs.) Not only is there lots of mouse under the hand, Func has also sculpted channels for all the fingers to rest on the top of the mouse.
Faintly visible in the gap of the top piece and the side piece are the 3 sensitivity indicator red LEDs. The DPI levels can be set in the mouse software. There are two LED light zones that can be customized in the mouse software with RGB values. One is the scroll wheel and the other is the Instant Aim thumb button and the colors and pulse effects can be assigned independently.
Also visible in this image and the one following are the four buttons that can be accessed by the thumb. Every button on the MS-3 mouse can be customized. This is perhaps the first mouse that places a button on both sides of the thumb well, though the button on the edge of the thumb rest is the least accessible. Func seems to realize that button’s limited utility as it mutes volume by default – something you won’t often do, but nice to have within reach.The MS-3 is best suited for the palm grip where the hand and fingers rest on top and make full contact with the mouse. Take into consideration that this is a big and heavy mouse.The textured scroll wheel rolls with tactile bumps and as a button, doesn’t require excessive force to press. Near it along the line between the primary mouse buttons are two buttons. All the mouse buttons and the scroll wheel are programmable.Here’s another look at the molding. Also visible is the single side button to the left of the left mouse button.Observe how the fingers are to rest flat on the mouse.The MS-3 mouse has a 76 inch long braided cable (6.3 ft / 2 m) ending in a gold plated USB plug.
The underside of the mouse has four feet that allow for consistent gliding. Also visible is the laser sensor that can track up to 5670 DPI.
