Actually I do not think so much of it, if the seller comes from China. However, I must confess here that the lamp makes a very good impression on me. The assembly is very easy. The holder is simply fixed to the glass with two plastic screws. Afterwards you put the plug in the socket and switched on. It has three possible settings. First, turn on, then turn off and the blue diode so. From my side, this LED lamp gets a buy rating.
