I've tried gamer mouse in my life, but this is by far the best. Razer tends to make a mouse that fit all hands except for small and was an ordeal for me. I try the RAT 5 which was not bad, but impossible to reach the red button to slow the mouse sensitivity in. So I opt for the 7 and the fact that the left side of the mouse, be removable completely changes the game. I have never been more in harmony with my mouse into play with that one. more customization of parts with anti-slip material is in the box and it's just perfect when you have sweaty hands after a few hours of intensive games. I recommend it, and it was worth every penny
