I got this as a birthday gift to my wife, and it worked great for the first 2 hours. Then the thing wouldn't turn off. In the middle of the night, to get the light off, I pulled the battery. Now the thing won't turn on (yes the battery is back in). I suspect that the problem is in the switch, maybe a lemon, or maybe its just a piece of junk. Eitherway, its junk to me now.
