Although the mouse itself is nice to use, I find that it often "disconnects" and takes several minutes (and lots of fiddling) to get it working again. I'll be doing something, and then suddenly the mouse no longer responds. I'll try pushing the button on the bottom a few times, I'll access the mouse properties (using the trackpad on my laptop), I'll restart my bluetooth services, I'll do a combination of those. Sometimes it takes 30 seconds, sometimes it takes 5 minutes. I can't take the frustration anymore, so this is going in the trash and I'm going back to my Logitech wireless USB mouse.
