I got a wireless keyboard and mouse because i kept trippin over the wires (im sure anyone that works on a few computers at once knows what thats like )

Anyway at first it was great but then my mouse started screwing up and i couldnt figure out what was going on (it was 4am ).

Anyway i figured out that it was the batteries (duh).
at first i thought "cheap manufactures batteries" and put some new ones in.

but the batteries only last about a week in my mouse anyone else had these kinda problems???
