Thanks Caper!
Yes it must be the same company as they do sell portable infrared saunas too and the chi machine I'd get would be from Australia. Maybe they're cheaper in Aus as we pay extra for the shipping? Unless the price has gone up, when did you get yours? Also the company say cheaper ones could cause harm as they're not made in the same way, though they would say that I suppose ;)
Anyway, thanks for offering to give me yours!! Shame I don't live there! Perhaps you should try and use it, it's supposed to help with relaxation and energy which would both help if you have kids!
