Any Wireless Mouse Recommendations?

I do not have a wireless mouse (nor do I need one), but my wife has one and it is rapidly nearing its end-of-life. I can tell, because of the number of times she smashes it down on the mousepad in frustration. She is not alone in her anger, as evidenced by the large number of mouse smashing videos on you-tube.

Anyway, does anyone have any recommendations? Important characteristics are long battery life and connectivity that is constant (perhaps those 2 things are mutually exclusive?). It only needs range of 2-3 feet.

I already looked at lots of reviews on Newegg and via Google. My favorite is an article entitled Information About A Wireless Mouse. Its my favorite because it manages to say absolutely nothing, in a nice short 5 paragraph article. I wonder whether it was written by a software application?
