The only complaint about this mouse is that middle clicking on the scroll wheel is a bit of a 'hit and miss'.

Has been working great ever since I received it. Battery life is long and efficient and it has its own port to place the USB Bluetooth hub for easy storage when not in use. Batteries are included so that is also a plus

I hope Microsoft will consider a new material for the wheel grip. After just over one year of daily use, the wheel began sticking. Scrolling the wheel came with a lot of resistance. Another 6 months later, rubber shavings have nearly plugged the gap on either side of the wheel.

This recent purchase was for replacements for three existing mice. I have found them to comfortable and easy to use. My only criticism and the reason I replace my existing ones, it the rubber band around the wheel deteriorated and became loose so the wheel no longer functioned reliably.

I've tried, butnever been able to ditch the mouse and use the touchpad exclusively. I used to buy expensive Logitech mice, and each time they would fail after a year. The computer support person at work recommended the Microsoft mouse. I had my doubts, but he was right.
