All are crap as they are made in China. I have worked in one of these kinda of company before. Try visiting the HQ of Ogawa, you will see the lobby full of spoilt massage chairs.

The japanese made chair is better but the air bags are defective after 2 years and need replacement. They made the seal using rubber that dries out after 2 years then the air bag used for massaging cannot inflate.

A big waste of $$$. The japanese company that makes it is obvious making it to die after warranty to make you send it for repair and get $$$ from repair service & parts.

Don't buy. Buy something cheap and simple like a massage bead cloth thingy they put in car seat or something because the massage chair will breakdown and cost $$$ to repair.

Breakdown as in air bags. The other parts are not easy to spoil except maybe the China ones as my boss said stay away from the made in China crap.
