Just searched for vibration plate and found this thread.
I have one at home and couldn't be happier with it! I'm getting married in August so i hired one from a company near me in Manchester, (but i think they cover all UK) i've been using it 3 weeks and already noticed a difference!! I wish i'd known about it earlier!
I absolutely love it! Don't think i'm bona let it go, and keep on renting it!
I found the link for the website here lf2.co.uk.
Have a look girls, cause you won't be disappointed!
