👍 everything you would want and expect from this.
Love this even though it’s a standard bit of kit. I bought an American toothbrush charger, 100v over our 230v. Checked if the toothbrush would accept this etc.. and it works like a charm. Finally can use both sockets in the bathroom, need to get around to testing if both can be used at the same time. Good price point, looks good inside a vanity cabinet, 5 star for doing everything I would expect and wanted.

Good looking, high quality, but with a couple flaws
The matt white effect is lovely (although it’s almost more of an eggshell than a true matt), but I do question the choice of a clear plastic backing (white would blend in better). My faceplate also came with a very small flaw in the paint. Not enough to warrant a return, but worth a mention. Also, a note on installation: do not over-tighten the screws, as it is possible to deform the mounting bracket, making it impossible to have the cover sit flat. If this happens, back out the screws a turn or two and try again.

Incorrect double socket identification
These electrical sockets are not Screwless as advertised. Have now sent two back. It looks like they have been identified by the manufacturer with the wrong ident number.
