"These sockets may look OK but are awful from an installation point of view. The Terminals are small and not very robust, expect problems if you have a spur off a ring and more so on a radial circuit. The fixing screws are non standard countersunk and do not finish flush to the front plate. The chrome metal front plate is so thin it distorts easily and looks dreadful on a polished finish. I will not be buying these again !"
