Anyone got Babyliss Straighteners and the handle stays warm when switched off but still plugged in?

I've got the Pro 230 Elegance Straighteners and the section of handle where the function ons are, stays warm when the straighteners are switched off but still switched on at the socket. I have found a review for the standard Pro 230s which says the same and apparently Babyliss are aware of this problem but say the straighteners are still safe. I'm not convinced and don't like the idea that unless I remember to switch off at the socket, I have a pair of 'warm' straighteners at home when I'm not! I've seen loads of reviews about how well these straighteners perform (and yes, my hair is in better condition than with my old GHDs) but have I got a duff Babyliss pair or do other owners find the same problem?
