I like these little stick on lights. I put them in a closet and they are fairly bright. Very easy to use. My only gripe is that the back casing is not too sturdy. I stuck one on a wall but decided to move it one day. The case broke and now I have to tape it in order for it to stay on. Basically, once you stick one of these on a wall, they are there for life unless you don't mind breaking it. The back casing turns about 1/4 of a turn to lock in place. I wish they used some other method such as with tv removes (the little laches for example). That would be much better.
