Probably the cheapest silent mouse from Logitech, won't work with Unifying Receiver
Reviewed in India on 24 January 2019
Looks pretty much like the M185 mouse - this one has silent clicks and scrolling but doens't come with or work with the Unifying Receiver.
The scrolling sound was a little louder than the M330 which is costlier but has a more ergonomic, asymmetric shape and also works with the Unifying Reciever.
If your need is a quiet mouse and don't want the Unifying capability (connecting up to 6 devices to the same receiver), this is the one for you.
