I tried writing to several socket cover companies a couple of years ago, my experience was similar to fatallyflawed. I got the impression that none of them really had the first idea about electrical matters. One reply, from Safetots, really took the biscuit - here is an extract:
"Although we understand that the vast majority of homes are fitted with the 13-amp power sockets, unfortunately this is not the case with all homes."
Now, I ask you, what is the point of saying that? Neither Safetots nor, as far as I know, any other company sells socket covers for older round pin British sockets - but if they really think older sockets are an issue then why not?
Another thing which really highlights to me that none of these companies know what they are talking about is that they often have instructions on the packets saying "switch off the socket before fitting". Apart from the fact that not all sockets have switches (and when BS 1363 was first published it did not even allow switched sockets), if they had any confidence in their product having some benefit, they would not write such nonsense.
