The Anywhere MX logitech mouse served me faithfully for 7 years, where it just didn’t go, but it was overtaken by a double click (and judging by the reviews, I don’t have one). Began to look for a replacement. Logitech quality is very poor now, so the only normal small wireless option is this RAZER. It is certainly not as comfortable and functional as my previous mouse, I would give 4 stars, but of all the options on the market, this is the only normal one. And I really liked the opportunity to work both through BT and via the transmitter. No need now every time to stick it into the laptop after carrying. It will fit just like a small portable mouse and you can play with it quite conveniently.
