Review on Logitech M171 Black and Blue RF Wireless + USB Optical Mouse with 1000DPI, Ambidextrous Design by Velizar Stavrev ᠌

Has some pros: Design, low profile, compact and lightweight, silent scrolling. There are no problems with accuracy and work without a mat. The surfaces of the sides and the wheel do not slip due to the convex pattern, and not the rubber bands that could spread over time. Cons below: A few months after the purchase, the scroll turned off - you know, the standard problem is when you turn down, and on the next “click” of the scroll, the page jerks up, not down. And then down again, and then up again. And maybe after one scroll twitch up and down. This happened to me on penny A4 and Genius after 3-5 years of work (wear of a mechanical encoder), and here - Logitech in the very first year. Fu be like that, Logitech! I dismantled the case - there is no dirt or debris inside, cleanliness. I did not expect such a setup from Logitech. I have already managed to advise several people, I even managed to buy another one for work - there is no problem with the wheel yet, but I am sitting with the expectation of a set-up at any moment.
