Adequately functional.
The downside is that the material on its sides wears out easily and tore.
However, it adapts to almost all surfaces and gets the job done.
It's worth it.

Unfortunately, it was not what I expected. I have had a Microsoft mouse for 3 years that was completely silent, and I thought this one would be the same (it looks the same). But unfortunately, it's not. The buttons make quite a bit of noise, at least for me who was used to the silence. The scroll wheel, however, is silent, the buttons are the problem. Apart from that, it works fine. For me, with large hands, it fits perfectly in my hand.

Very soon, both the specific product and the first mouse I bought and the second one developed a problem with the scroll wheel. Both scroll wheels, after a period of use as a middle button (so they were pressed frequently), eventually got stuck in the groove and do not rotate (or rotate without the corresponding result on the screen) and lost their function as scroll wheels. They were pressed and remained stuck in the groove and fortunately, at least they are still being used as middle buttons.

4 stars as I would like a slightly better dpi and also the keys get dirty very quickly for some reason.
