Does anyone know what this auto step machine thingy was I saw today?

Kind of looks like a reebok step but acts like a wobble board. So you switch it on and stand on it. It wobbles you about like mad and burns calories while you stand there.

I had a go and it was fun but £400.

Was going to research reviews but can't remember what the heck it was called and google ain't getting me anywhere.

Power plate?

(Disclaimer: haven't been to the gym for aaaages)

No it was shaped lîke a normal Reebok step but had switches.

I think it's a kind if surfing simulator but forgot what it's called.

Mmmm, it was more of a vibration action than a surfing simulator.

It was making my boobs jiggle up and down like mad and my arse which dh thought was hysterical.

Anyone? Think I want one now!
