I really miss the accuracy, 'work anywhere' performance, and heft, but not the cost and battery draining ability, of the blue light mouse that this unit replaced, This unit isn't quite as accurate or happy working on the glossy palm rest on my laptop, but it does just fine on most other surfaces, and is a joy to use with a mousepad.

Random clicks, a faulty scroll wheel, and unwanted double clicks plagued the unit

definitely not as bad as the first unit!

, some units leave plant defective or ill assembled.

I had this same unit for over 6 years and it finally died !!!

Both units hung up during scroll, jumped and consistently failed to stop scrolling
