Nevertheless, even if it is possible to customize the mouse quickly we reach only have one configuration of it and never change!
Regarding the comfort and robustness I shared.
On the one hand the mouse is very fine, it is a low profile, so you have to pay attention to this detail before purchasing because it changes dramatically mice more "thick" and it takes a good time for adaptation (see some people will not do it).
On the other hand, the back of the mouse, configurable in height and length leaves two holes in the middle of the mouse with edges of hard plastic that can rub on the ring and "hurt". We must learn to position his hand differently to avoid the edges of plastic. Note that the rear panel of the game he moves laterally when your hand is based on ...
I take it 1 star for this important points, I'll almost have to remove both.
I take him another star 1 for buttons to press on the two sides not conventional buttons but the buttons panels. It is clearly impossible to successfully press the right panel with his ear ... And when left to successfully use it we must completely change the mouse keeps so the button is difficult to press and especially keep pressing (case eg for use in the snipe FPS).
