Review on Logitech Wireless Silent Mouse M220 by Adam Kowalski ᠌

Pros include extremely quiet keys. The one AA-format battery merely sniffs. I never make more than one modification every six months. It is in use from 9 to 17 Monday through Friday. Cons of it: Nevertheless, the left button started to malfunction after working for about 5 years. I purchased the same one, however the scroll now makes a somewhat noisier sound as if it were rubbing against something.
