The sockets are fine and reasonable quality for the price. The big problem with them is that they don't fit into the back box. I had to cut out parts of the back boxes to get them in. My house is 1960s but would have thought things haven't changed too much with sizes. I'd also bought the one with USB sockets. That is even bigger still.
Always a good fit and finish. Chunky switches feel good quality. We’ve had a dozen or so sockets and switches for different rooms, never had a bad one.
