This light worked fine for the first 3 weeks I owned it. Then, it fell off my commuter pack somewhere in transit. I worried about this happening, given how basic and loose fitting the clasp is. A better design (like Light and Motion) would snap the clasp in place after attachment to loops, hooks, clothing, etc.
The light battery charges easily. It seems easy enough to remove the light from the harness and clip it on your person. I was expecting it to have a pulse setting and was surprised to find the wasn't available. It seems a fair price $30.00 if it lasts for 3 years with regular usage.
Easy to connect and disconnect from your bike with the rubber mounting strip. Plenty of light selections and the lightweight is a plus. Easy to recharge. So far no negative points yet.
