I play a lot of different games so I need as many buttons on my mouse as possible. I had a g502, and then when I saw the upgrade, like any serious gamer, I needed 'better'. Laser and precision are the best I've touched. BUT! Need to add this laser to the g600 mmo mouse and/or slightly improve the button layout for short fingers. I often press extra buttons on my mouse and the thumb button causes me to hold the whole mouse in an uncomfortable way. In summary, if frames per second are your thing, this is the mouse you want, need and should have. If you're all about Warcraft or some other MMO that's coming out, not so much.
