Query: Cute idea, but cheap workmanship. Disappointing!

This light is just so cute, the way it silently glides open and turns on the light at the touch of a button! But then the single LED proves to be not-quite-bright-enough. And you can't really adjust the position, it glides back every time I move it so I can see the whole page. Now I'm holding it so I can read. Uh, doesn't that defeat the purpose of a clip-on book light?Then the light doesn't turn off when I snap it closed, and the batteries go dead within hours. And the only way to turn it off is to pop the batteries out - a few times doing that, and the catch on the battery door snapped off. It went in the trash.
