Do not waste your money on these, not as described, very cheap, hardware does not work. Going to have to repair my wall before I can do anything else. Completely unacceptable product. Very frustrating and was not properly represented in the marketing advertising. Do not buy. Would like to return, but waited 3 days to long. If I had opened them immediately I would have seen the poor quality.

Very well made and solid. All the parts fit together perfectly. Very convenient you can plug in a lamp and charge your phone with the usb ports. Great value for the money.
