Interestingly, the Rival 300 only allows toggling between two DPI presets (via a button just below the scroll wheel), which actually works out fine because I rarely use more than two DPI settings anyway. All six buttons are fully programmable via the excellent SteelSeries Engine software, which makes customising the Rival 300 (including the RGB LED lighting on the scroll wheel and the logo at the bottom of the mouse) a brilliantly straightforward affair. They’re all large and easy to reach in a hurry (with the possible exception of the forward thumb button, depending on the size of your hand), and there’s very little chance of any accidental button presses. Six buttons adorn the surface of the Rival 300, and their placement is completely logical. Simply put, it’s one of the most comfortable mice on the market, and using it for extended periods of time never produces any sort of discomfort. Its smooth contours lend the mouse a very natural, flowing feel, and on either side of it you’ll find textured grips that keep it steady in your hand. The long, chunky chassis has quite a high arch, which makes it great for anyone who favours a palm grip, but the Rival 300 is every bit as comfortable whether you favour palm or claw. my firmware version is now 0.37.0.0 and will see what happens. 5) update firmware as recommended by the SSengine 3.5.2. Its design is specifically tailored to right-handed use, so lefties are probably better off looking elsewhere. 3) unplug mouse, press Left mouse button+right mouse button+ DPI button at the same time and plug again while pressed (it should start blinking blue when connected) 4) install the 3.5.2 engine.
