Review on Logitech M220 Silent Mouse: Wireless Blue, Noiseless Operation - 910-004879 (Blue) by Wiktor Kosiorek ᠌

The keys are remarkably silent, which is a huge plus. The single AA battery barely makes a sniffle. The most frequent time I make a change is every six months. Monday through Friday, 9 to 17. Against it: However, after around five years of use, the left button started acting up. I recently purchased one and noticed that the scroll makes a little noisier shushing sound as it moves.
