Bests & Worsts Reviews from Amazon

I did love this mouse. It worked on a number of surfaces, connected quickly, and scrolled smoothly. HOWEVER, do not buy a mouse with a Unifying receiver if you plan to use it with more than one computer. Directly from their website: "Some Unifying devices have a limit of forty-five (45) unique connections. If you're using such a device with multiple receivers, once you connect 45 times, you won't be able to connect to additional Unifying receivers." ... "Because your mouse is switching between two Unifying receivers, each time you connect, you use one of the total available connections. Eventually, you will hit the connection limit." Not happy. This was nowhere in the instructions and it would have been great to know BEFORE I used up my 45 connections. Since my old laptop has since died and that was the 45th connection, I have a useless mouse now. Granted, I don't know much about electronics, but this seems like planned obsolescence to me...
