"Sockets are smart when on the wall. Not hard to install and the front plates click on fine and aren't that hard to fit on normally.
If you're never going to remove the sockets from the walls (eg for decorating) then they're nice and reasonably priced. However once you take the plates off, it's very tricky and in some cases impossible to get them back on properly. So for most folk they're going to be a real pain, so I can't recommend them at all. Avoid!"
