The scroll encoder is a problem. After a month or two it becomes impossible to work. An autopsy showed that the problem is mechanical and is solved in a good way by soldering the encoder to a new one, because. used the cheapest and lowest quality option. I don’t have time to look for spare parts and do preparations, so the mouse itself, alas, becomes a donor of details. If the matter does not rest on the wires, it is better to take a wired one. I think you can find cheaper and better quality.
