About a year later, the famous scroll glitch began, when you scroll in one direction, and scroll in the opposite direction. Changed under warranty for a new mouse (glory to the Logitech service). A year has passed, on the new mouse the same malfunction. Those. the marriage is massive. I will return and probably ask for a refund. In general, a little disappointed, because. for more than 15 years they have been buying exclusively Logitech peripherals, and did not expect such a catch. If I want to change the mouse every year, I will order a a4tec. I didn’t think that I would ever have to write such a thing about a device from my favorite manufacturer, but I strongly DO NOT recommend this mouse for purchase.
