Hi all, Looking for a mouse with the following specs, any suggestions welcome! Wireless Comes with a charging dock, or can be connected via USB cord to charge Has 5 buttons Its for general desktop productivity so no need for 20,000,000,000,000 dpi etc just bog standard optical Doesn't cost the earth (cos work won't pay for it and I'm stuck with a crappy 2 button corded mouse) Cheers
