The partial driving me insane!

Bin for many years always been very satisfied with keyboards and mice from Logitech, especially with the cordless versions.
But this not exactly cheap laser mouse is an absolute disappointment for me. Permanent dropouts and random double clicks, and especially frequent, uncontrolled auto scrolling make particular working in Excel files virtually impossible and causes me now tantrums. Thought to be an "outlier" and bought the part again. After a few days the same problems.
So despite good facilities and great design: in practice, useless, alas!
