Our pugs are actually safer because you can't pull them out by the flex, 
so you don't stress the chord or pull the wires out of the plug. All 
plugs are easily removed though. They just pull out. The switch turns 
off the power when not in use. Otherwise the outlet is live, even with 
nothing plugged in. That is just insane. It's pretty hard for a child to 
electrocute themselves with a UK plug socket because of this and the 
shutters. People still use covers, but need them a lot less than in the 

I can also walk in to any hardware store an buy a replacement plug and 
fit it, should I want to. European and US plugs always seem to be molded.

Yeah, really expensive ;-)

Yeah, we have those too. You did read about the limitations though?

So, really you need a fuse too :-)
