It is expected for a low price no Topware - but: Expect one can know that even such a China-products at least works! But he does not. So complain. And here we go: We play so much on time and mailed with the super translation tool from Amazon back and forth until you have to stay with it at some point can not be bothered more. It reinforces the impression here is with cheaply made electronic money with delivery times beyond good and evil. I've learned my lesson and have (not quite) invested 30 euros for a "real" lamp. If I could give no stars - I would do it!
