Hi. May I know what's the best long term wireless mouse?

I own a wired Gigabyte M6900 and i'm very happy, but because I use a laptop and am constantly on the move (its been nearly 9 months now) I think that for convenience sake a wireless mouse is better for my gaming on the go (and working on the go) needs, so I won't wear down and destroy my wired mouse unnecessarily.

Any advice please?
