Yeah the logitech ones are (from what I know anyway) the best on the market for portable wireless mice, and their new-ish range have micro USB's which are like half a centimetre long, so it's pretty impossible to break them. I have an M305... will jsut find a liiiinkkkk

It's really useful cos it's quite small but very ergonomic, and like I said the little USB is a god send <3
i paid like 20 dollars (15 quid at the time) for mine so count yaself lucky ;ll). TBH, you could probably find them on ebay or somewhere for a little cheaper, but seeing as your laptop was in PC world too.. :P
