US water-pik system--should I bother bringing it to the UK?

Maybe that makes a difference.  Like I said, I don't know; I just remember it being a bit thing in the 80s.  I'd probably take your dentist's recommendation over mine.

Well, you're not the first person I heard that from, plus I have also heard it from someone's dentist as well.

Sometimes you're damned if you do and damned if you don't.

They have never not been around.  My parents have always used one, I tried and foundmy teeth became more sensitive.  I think it depends on your teethy issues.

I just received a reply to my query from Waterpik tech support.  They didn't actually tell me the type of motor employed in the WP-40W, but said they do not recommend using it on other frequencies, which suggests it may well be a synchronous motor.

They forwarded this link to the U.K. distributor for current 240V 50Hz versions:

Thanks for your research, Paul.  I will just get one in the UK, then.
