This is first product, I am using from JSB. I was looking leg massager, which has warranty and you know some one, who can be contacted in case of issue. JSB fulfills my needs and I ordered and got the machine. Main objective was to find a machine which can give some relief to parents. About the product now: Product is working completely as it was expected. This machine comes in ready to use state. Just open the box, plug in to power and start using it. Keep you leg in it and select any of 6 options(in total) and enjoy the great massage. It works very well for massaging the leg in 6 different option(3 for massage and 3 for vibration). Overall, suitable product for elderly people and gives good feeling after massage is over.
