Review on Logitech M220 Silent Wireless Mouse, Graphite by Ivan Atanasov ᠌

If there is a free usb in the line of sight of the mouse, it will do. Otherwise you can't take it. The mouse itself is good, but the signal quality crosses out all the pluses. Has pros: Really almost silent The wheel works on an optocoupler - it will not die in half a year. You rarely see this today. Cons: signal quality. If direct visibility to the receiver - the rules work. If stuck into the system unit (despite the fact that it is on the table, sideways to me and to the mouse) - the cursor freezes constantly. He sinned for the lack of grounding, the same thing with him. Sinned on the power supply, he also did not have anything to do with it. I had to bring it forward through an extension cord, the problem disappeared. Before that there was a rapoo 1090p mouse, before it was a genius navigator 905 - they don't have this problem. By the way, logitech m170 is the same problem.
