I've stopped buying read-made ones. I buy the 4-way trailing socket (of a
known brand), a 13A plug, and a length of cable. And wire my own. It's
the only way I can be sure it's done properly. And then I test it. Not on
a PAT tester (I don't have one), but by measuing the voltage drop across
the cable with a significaunt current (10A-15A) passing and then a megger
test between the current-carrying conductors and the ground conductor
(normally at 1000V). If there's _any_ sign of problems I investigage.

That probably wouldn't count as an official test, but I trust it...
