The machine invented by Keiichi Ohashi and manufactured by Skylite Ind. Co. Ltd is only sold in Japan. Skylite granted a licence to a Taiwanese company called Hsin Ten Enterprises (HTE) to manufacture and market the same product outside Japan. HTE began selling their product under the trade mark “Sun Ancon” more than 25 years ago. It is manufactured in a factory in mainland China.

When these machines started becoming popular in the West, they became popularly known as “chi machines”. The President of HTE later registered “The Chi Machine” as a Trade Mark.

HTE still sell the original “Sun Ancon Chi Machine” 25 years later, using the same basic engineering specification. Unsurprisingly other companies have developed variations on the original design – some of them with more basic engineering, some of them with more advanced technology.

We do not sell the Sun Ancon Chi Machine on this website as it is much more expensive than other models, and the top models available on this website are in fact more advanced, with more robust motors. The Sun Ancon has an AC motor while the FlexxiCore, the Surge of Chi, and the Vitality Swing all have heavy-duty DC motors.

The good news is we sell these top chi exercise machines at about 50% of the price (or less) of the Sun Ancon – which retails at over $600.
