This is a great simple unit to use: it is switchable to motion sensor, on, or off. It recharges via regular mini usb (which everyone has because of their cell phones). It is really bright; surprisingly so for its size which is about as long as a stapler, but it is thin an light. Mounting is easy, particularly as you have numerous options of mounting by screw or double sided tape. The motion sensor worked pretty well at normal distances, but occasionally did not work from further away. Given its size, I expect this is only meant for smaller spaces.
In all, a really great rechargeable light, which I received for review purposes.
