I have a logitech LX7 now. It lasts way longer than other mice I have had.
It doesnt have the recharger cradle, but thats fine with me cause I always
had problems with those. I keep a battery recharger behind my desk with 2
spare batteries topped off. Even using the rechargeable batteries it goes
about a month of heavy usage before I swap them out. I guess if I used
regular batteries they would last 6 months.
