This mouse has been able to wistand my abuse even after 2 years of use. I use it for normal computing and gaming. The mouse is pretty big, for me that is a plus, since I have big hands.
The SetPoint software that it has, you can customize it by having 5 different speeds and changing them with just clicking the button in the mouse. This is especially a nice feature when you are playing a game and you have to make a precise shot, just slow down the dpi and go for it. To me this feature sometimes helps in normal computer use also.
The weight changes is a "nice" feature. But you easily can adjust to almost any weight you choose pretty quickly. So it is not that important.
To conclude, this mouse is great for playing games and just normal computer use. Highly recommend it.
