Near perfect
Honestly, it's great.
It's perfect for my hand, it feels like the wrist is rested.
The mouse is not too heavy and the removable thumb rest is great. It's hard enough not to move during normal use and soft enough to move it voluntarily during use.
We can position it as we wish.
The fact that you can adjust the tilt is a trap. I would have preferred a perfect angle and we talk about it more. Here, we don't really know what angle to give the mouse. But hey, it's better than a fixed angle which is bad.
The fact that you can adjust the sensitivity of the mouse is good. But the steps are too small... The precise, normal and fast modes would have been enough. There are far too many notches here.
Finally, the buttons. The fifth button is hard to reach but in real life it's fine. You get used to it as you use it. And to be honest, the right click on the ring finger scared me. But you get used to it very easily and very quickly. It's strangely natural to click with the ring finger!
That's it! Very good mouse that I recommend.
