For now it glides quite well, I can not be specific about the problem in the FPS for example. The grip is very good and access to 7 of the 9 buttons is truly ergonomic (both below the wheel much less, best used to change the dpi and / or profile).
The driver is really very simple (I said that we must download the Internet) and French. You can change all the buttons without problems, there is an option to assign a mouse button by clicking on the keyboard, for example the key above the knob to space, everything is possible.
One star less because the mouse is a little low cost on the matter, the click of the wheel not super nice and the wire laced shoe that time by clinging to my furniture but very rarely so far. It's a bit of haggling to 32 because I'm happy, I expected it to be this ergonomic mouse while offering lots of buttons, it does.
