"Excellent in all respects."5.0 starson by frihet2
Pros: High quality build, great tactile feel, on-off switch.
Cons: I can find nothing to complain about. Someone else might think it is a bit too small.
Summary: I did some reading before I bought a BT mouse. There are problems with some. This mouse connected quickly, stays connected, and exhibits no jerkiness or strange behavior. I'm using it on a Lenovo ThinkPad Edge 13.3 (Intel) running both Ubuntu 10.04 (primary) and Win7 Pro (secondary). It works just as well in both environments.
