Comments on a mouse on an online store:

XHH: To be fair, it’s worth noting that the v-track technology works just fine. I have to work in bed, but I do not experience any inconvenience because of this.
On the box it was written that the mouse works even on the fur surface and it really is. I tested on a home long-haired cat - the result just struck me. Oh, if she didn’t roll, that would be a carpet!

WOW: I bought this mouse today, tested on my cat, it really works. I recommend this model to all cat owners.

zzz: I wanted to buy a carpet, but after your murderous comment)) I will buy a cat!
