VERY CHEAPLY made.  Arrived broken.  The outer housing is a soft plastic and bends all over the place.  Mine was so easily deformed that one side was broken off, so the outer housing was hanging on with only one anchor.  Furthermore, the electronics, when plugged in, did not work.  My recommendation is to go to the local hardware store and get one.  The low price of this makes it look like a great deal, but it is just money thrown away.  It arrived in a nice box and packaging with NO evidence of damage, so I am not sure how it was broken.
