Going off topic here.
Ragnar, you gotta remember that quite a lot of consumer electrical accessories are sold here without any safety agency testing - some of them even have forged certification seals.
I could show you dozens of extension cords, plug clusters, attachment plugs, sockets, etc. that bear no markings at all. Most, if not all, of this stuff is manufactured in - and imported from - People's Republic of China.
Sometimes, also, the quality of the legitimately marked items is so shoddy (socket contacts that grip so loosely that the plug just slips out) that you wonder how they ever got the certification seals.
