Got these to replace some 30+ year old MK metal sockets which were still actually ok but the decor in the room was changed.These Knightsbridge double sockets are really good quality.These Knightsbridge sockets have DP (Double Pole) switches which means Live and Neutral are cut off when switched off unlike SP (Single Pole) switches which only cut off the Live when switched off. SP is safe but DP is safer on sockets especially if you're like me leaving plugs in all the while.When replacing these switches, the likelihood is that your switches and house are not brand new, which means that you might find your old switch connections are completely different to these.I found that the connections were in opposite locations compared to my old switch cover, which meant I had to move the wires in different directions. Bearing in mind the wires are not exactly unlimited in length, it took me nearly an hour to do one because of the length of existing wire and accommodating the new wire position. In one instance, the wire just wouldn’t stretch over to the opposite side so I’ve had to extend the earth wire so that the switch is safely earthed.Be prepared for a lot of swearing, time spent and some problem solving to fit these, you may need the help of someone more competent if extending wires feels uncomfortable. Plus side is that they look way better than the standard white plastic switch cover.Advertised as brass, but is really plastic with perhaps a very thin layer of brass on top. Kept, since I only needed the internals to repair a broken wall plate, but would not order this one again.It’s probably better (once life is back to normal) to go to your local DIY shop for these kind of things, so you can see them before you buy.1st one I bought, 2 of the switches wouldn't dim at all. Amazon let me keep it, and gave me a full refund, and I purchased another one.This 2nd one, there was one switch that constantly flashed no matter what I set the max and min dim to on the rear of the socket. I switched it over with a working switch that I still had from my 1st purchase.Not great considering the price of these things. Although they are one of the cheapest of its kind on the market, you'd still expect it to work properly.UPDATE. 2 days in, and another switch has started to flash. Only when it's been off for a while. Once it warms up its OK. Wierd! Going to swap that switch over with the final working switch from my 1st purchase. Not good Amazon/knightsbridge.At first glance it's a nice, solid piece, feels strong when you are working with it. Won't fall apart that's for sure.When you try to mount it onto the wall:-you realize there is no cable management option on the back to hold the cable tight in the wall-the paper slides out from the window and falls onto the floor. There's a big gap behind the transparent window.When you try to use it:-the ethernet cable simply pops out from the connector. The reason is the sliding door on the front. As the spring is strong and the door has a sharp edge on the bottom, it simply prevents the ethernet connector to be fully pushed in (shown on the pictures) and lock. You need to use both hands: 1 to fully push up the sliding door (probably with nails), other one to push the cable in.It's a nice piece, but I have the feeling that nobody tried to use it before releasing the product. Another disappointing piece from Knightsbridge, but at least this one comes with long enough screws and good paint quality.Wall socket with USB:it's too noisy, I have to replace all sockets with USB from this brand in every bedroom. With this high pitch noise it feels like sleeping between angry cicadas.
