Poor 90

Coming from a Logitech MX Performance jespérais find quality mouse, after a month of use:
- It is beautiful but it seems that it will disintegrate when touched
- Very bad ergonomics for my hand despite the pseudo-2 settings axes
- Autonomy: there is a ?! it takes just half day office use
- Every two hours one must make a turn in the pilot to reconfigure sensitivity because she won ... for supposed mice have an accuracy of hell: buhahahahaha

So I am not happy with this mouse, even at 20 it's still too expensive because it is just plain wrong
