Switches on without motion ...

I have the lamp for some time now in use. So far, I was very satisfied and can do a lot of the other reviews only underline. Light enough and quickly jumps in movement. The lamp can be mounted with screws or glue - or simply to metal, since a magnet is attached. Bonding, however I would not recommend it because the lamp is quite heavy and has the adhesive strength was insufficient for me.

But unfortunately occurs after a while with me the same error, as with many others here: The light turns on automatically, although no movement takes place. Thus, the auto function is totally useless with motion. I will send them back. Pity!
