Batteries

I have gotten a wireless keyboard and mouse for my PC. I've had it set up for about 3 weeks, and in that time I have had to change the batteries in the mouse 3 time...been using Duracells.

Does anybody know of batteries that really last, or I I doomed to go broke on batteries?

Thanks

You really should be using rechargeable batteries. Get two sets then you don't have to worry about how often you have to change them out.

Something's wrong. No way a wireless mouse should chew up batteries at that rate. I've used wireless mice and trackballs for years and never had to change batteries more than once or twice a year. Maybe take it back and get another one?
