I had to replace my Razer DeathAdder because the scroll wheel started going bad. I kept hearing about the sensor in this mouse, and decided to try it. I mainly play Battlefield 4, Unreal Tournament 2004, Defender's Quest and Minecraft (with the kids / family), and I had been liking this a lot. The mouse itself is small and pretty light. The 3 buttons are very easy to press, and you can really hear and feel them when you do. The main buttons are very clicky and tight, and very satisfying to use. The two side buttons are much smaller than I thought they would be and are way harder to press and not nearly as comfortable to press as the DeathAdder's side buttons. They're way too thin and too high up for me to use as effectively. In shooters, I use the more back button to crouch, and the more forward button to go prone. It's not hard to use, just not nearly as good as it could be. This is the only reason I don't give this mouse 5 Stars. The DPS switch button is very easy to press when I want to press it and I haven't hit it on accident after a few hundred hours of gaming and many more hours in general use. It's light-weight enough that I haven't ever had a problem doing quick turn around shots, and it makes flying helicopters much better than I thought it could be. It has an RGB light on the palm and back part. It just drove me crazy, so I just made it purple and dim, just so I can find it. You can make it breathe, change color, stay solid, and adjust the brightness, which is good. The DeathAdder I got, I got with no light on it because I am not a fan of lights on mice. I do love it on the keyboards though. All in all, this mouse is easy to use and to take with me to work, and it's actually much better than I thought it would be. It's smooth with very good buttons. Just wish the side buttons were bigger. Not only would I recommend for a friend, I bought an extra for a friend and he really liked it as well.
