I won this mouse as part of a FB giveaway and the drivers and software have major issues. Disconnects are common and it is extremely painful. Other than that, the mouse is really nice but there's no point in having something nice that only works 80% of the time.

Don't buy it if you plan on using the mouse wheel at all i haven't even been using it for one month and the small plastic hex axle on the mousewheel gave out if only it had been made of somthing sturdier no point in getting it RMAed as it will break again soon

Got it for free as part of promotion. Would not recommend. Pros: -Lots of customizable settings that's saved to firmware -RGB -DPI shift button easy to reach Cons: -Giant bulge makes it somewhat weird to hold (personal preference) -Started having LMB double clicking issues 2 weeks into use. I did not even use it for any clicking-intensive games. -One of the two thumb buttons on left side is angled in such a way that you have to really push the mouse hard to the right to click it, so that you cannot really bind anything to it that requires the cursor to stay still.
