It works, but I don't like it
Battery life seems very short. I only use Rechargables and maybe they just aren't for these lower power/long time items (unlike camera's), but I am annoyed at how often I need to change them.Also, the unit is heavy. Of course, this is because of the batteries, but I didn't realize how much lighter my replacement logitech wired optical mouse would be. I like it much much better.Only buy an cordless if you really need it, would be my advise.
