Auline Convert Single Flush Mounted Single Socket to Double Gang Twin Plug Mains Box

Good quality and does the job perfectly.The only minor issue is the 4 raised posts where the metal base plate is attached to the box. It's probably not a problem with most sockets but the one I was fitting is a smart socket with built in wifi that wouldn't quite fit due to the posts. It was easily solved by 3d printing a spacer (you can also buy them from most DIY stores or Amazon) to go between the box and the socket but probably worth bearing in mind if you are likely to fit a similar socket.I'm leaving it as 5* since the fitment issue is probably specific to my socket and a regular double faceplate would fit no problem.

It does exactly what the advertisement said it would do no more and no less at a very reasonable price

Great for converting single to double switch.

It came on time and was easy to fit it will take double socket to plug your bits in.Dave J
