So why only 4 stars? Yes, I know, I'm a bit harsh, but there are 2 reasons for this:
1) The rubber coating that surrounds the mouse already has some traces, and I have a feeling that this is final, much like these touch screens that are full of fingerprints ... So the mouse is a less chic.
2) The wheel is a nice little noise: it could roll with a slight imperceptible noise, well no, it rolls with a slight scraping noise ... When using the mouse all day, we are attentive to such details insignificant.
