Christopher 3 The black plastic on these wall plates are a little too weak and some parts of the wall plate are very easy to break - which then makes them useless. The wall plate is held in place by a screw which pulls a piece of plastic tight behind the wall. Unfortunately that piece of plastic breaks extremely easily, and so you can either be super cautious, in which case the wall plate is loose - or you make it tight-fitting, but risk the piece of plastic breaking. It was a little frustrating to use these.
