Hypoxitherapy - cellulite cure?

I really would like to find out more and especially hear from those that have either tried or know someone who has used the Hypoxi system before. Cheryl Cole and Robbie Williams both rate this system so much with Cheryl claiming that Hypoxi is responsible for her cellulite free behind and legs. Please let me have your thoughts on this and in the meantime more info can be found on hypoxicentre.co.uk - I am seriously considering giving this a go although can be quite pricey!
