I had bought 2 of these mice two years ago, for myself and for a colleague. The first impressions were very good, but the bugs and problems are many for a 50 euro mouse, and for that reason, I DO NOT recommend it! In detail:
Aesthetically, it looks like a quality construction with nice and soft materials.
Very comfortable grip! (you get used to it in a few days) The click on the buttons is silent and very soft, smooth feeling.
The battery lasts 6-7 hours of work.
The optical sensor is cheap, worse than a 10 euro mouse on the same surface!
From the software, all the buttons can be configured, the LED color can be adjusted, and it also supports macros.
On the plus side, the packaging includes 2 covers for the back (the honeycomb and a plain one), so you can use whichever you want. The detachable wrist rest has not been comfortable for me, and I have never used it.
However, since the beginning, they have released various issues: The battery percentage is incorrect, as it runs out from 25% to 2%! Sometimes it freezes and needs to be turned off and on again to wake up! The LED light started to malfunction on one. The scroll wheel on one mouse is acting up, and on the other, it completely broke, and I had to return it because you can't work without a scroll wheel! The screen turns off for no reason sometimes and only lights up when you press a button momentarily, while on one, its brightness is dimmed. The button that changes the source often requires multiple presses to go to the next setting (sometimes it works on the first try, and other times it takes 10 presses!) Based on all this, I would say it is a cheap construction that they managed to make look quality!
