But a few quirks

The mouse works quite well so far, and the 360 ​​° mode. However, I do not have the impression that the mouse works better than a regular optical mouse (on different surfaces).
Negative points:
- Not particularly ergonomic, but you can see that, yes. The mouse rocker I find now not so very good ...
- Batteries almost scrap? For me, the mouse was hanging after a short time more than the charge lead that I've used wirelessly. With new batteries, everything is back on track.
Practically is definitely the built-in charging cable, even if I do something worries me about its robustness ...
