Almost bought one with the 12 buttons on the side but with nerve damage I csnnot feel them good enough to use them. I got a Corsair something or another because the two side buttons are high enough to miss my thumb when I grab the mouse, si I only hity them on purpose. I barely have to move my hand at all to reach any part of the screen, I did have to move it a lot more before. It is amazing, no more cheap mice for me.
