Good mouse for the price. At first there were glitches with side buttons - well, they didn’t want to work as they didn’t set up and rearrange fresh firewood . All the rest worked, but the side buttons, Mlyn, refused . I didn’t find a single similar description on the Internet, but in those. support is useless. I went to a friend - everything works . As a result, I used system restore from grief and wow! Earned.
