This mouse isn't worth $10.
It has a widely reported switch defect. My second one in the last 12 months has failed. The left-click double clicks on its own up to 25% of the time.
Logitech cheaped out a few years ago and went with garbage switches on this model. The Proteus Core that I had for many years was perfect (with the old switches). Do not buy a Logitech product with switches from this supplier.
