Have the mouse for some time now in use, for standard use this mouse is really great and served its purpose! As a large drawback therefore is also only 4 stars that the speed of the mouse each time to adjust when you need to reboot the PC or has time for some extended period of time. Since I the white level (3200 dpi), this is always permanent use to push a bit annoying for me the DPI button.
Optical mouse does something forth, the color change is a great thing and a real eye-catcher, the colors but you can not adjust it always remains the change.
On the whole I am satisfied with the mouse and I can this friend for casual gamers.
Who but "Pro Gamer" is this model would not buy! Since there are too few settings and a few buttons!
