A mouse really nice, large and heavy as I like, even if I do not have very large hands. Matter of taste. I took it because I like red when it flashes! Change the dpi easily it's nice if you want to make a little more specific stuff. I was hoping to customize the 3 colors of the mouse, but apparently not, we can customize one and the other two are installed by default in an order that escaped me. I managed to turn blue I do not like and there I fuschia red green, but if I change from yellow to fuschia, for example, I may have blue yellow green. One small "defect" minor: the small finger rests is a bit small, I think it's a shame, my finger overflows on all sides. As against the thumb is perfect (for me). So it may vary according to body types. But a really nice mouse that replaces my razer well a little tired. I program double-click on the Support button on the wheel, handy! Now it would take a notice of gamer in terms unique to gamers.
