We purchased this model, marked PMS through Cablestar, an online supplier, via Amazon. The packet was labelled “Mercury Telecraft Ltd.” The PMS cover has very short ”power” pins, less than 2/3 of the standard length! They do not reach the contacts. The earth pin length is correct, but it is 10% thicker than allowed by BS 1363. This will almost certainly damage sockets and result in a real plug making an unsatisfactory earth contact, which is very dangerous. The short pins make it particularly easy to insert upside down.
We have also seen this model on sale at Maplin under their own brand, as well as numerous other brands including “Eurosonic” and (from Amazon) “Status”. The “Status” packet is illegally marked “CE”, “BS5733” & “BS1363”, these marks are mutually exclusive, and non actually apply (there are no such markings on the product).
