At the gaming aspect, I do not see it: no adjustment weight, and mice is very heavy. The skiing is pretty bad, it "scrapes" too compared to Logitech and Razer (or other mouse worthy of the name). And the worst of the worst, impossible to adjust the dpi. What good gamer into a mouse? It is becoming too large, the shape is not ergonomic, and regardless of the length adjustment: medium or maximum length, impossible to reach the wheel, and short length, beyond the palm. It had to do more rounded in fact, higher. It is flat and wide, the worst form for a mouse, your hand is not maintained. Buttons are more wrong place, particularly the left of left-click.
In short, a product that was designed with the feet: none ergonomics, poorly placed buttons, unnamed ugliness and not adjustable dpi. Flee power.
