Query: Nice design but does not stay linked - do not buy

I bought two of these and they do not stay linked with the pc. I am constantly reconnecting them to the computer. I have to keep my old mouse nearby just so I can restart my computer. They go through batteries faster than any other cordless mouse I've ever had. It has a great look and feel but its functionality is not anything to be relied upon. Also the software is bad. I have to reprogram the buttons on every restart. I am going to return this and get a more expensive but ultimately much more reliable bluetooth mouse.
