Hi , Was browsing through Osim site re hand hand massagers/ I purchased an os3000 Ipamper heat and ions made in Singapore device 10 years ago. Absolutely awesome machine my dad loves it heat ions good. Highly recommended for all purchase once can use at home at time with friend. In having standard massages have to go their expensive also and therapist not qualified masseuses. So don't get proper massage. Machine hand held 2 speed settings and heat ions to assist circulation - leaving yourself fully rejuvenated after massage.
