Also, the receiver sticks out far enough to grab with the finger tips and comes out without a problem. It has a small groove around the edge which makes it easy to pick out. I got this mouse for a large part due to that. My work computer doesn't have bluetooth and I hate the dongles that stick out, and need to be unplugged, with other wireless mice. Leaving this receiver in at all times solves that problem for me, unfortunately it doesn't pair with logitech's previous products which don't support the new wireless method they're using.
