I bought this but never got around to giving it as a gift, so I just took it out of the box to try it. It's like new! (^ ^) It gently massages your knee with a gentle warmth. It comes with instructions, but it's just a matter of pressing a button, so I think even elderly people can operate it very easily. It wraps around with Velcro, so it looks a bit bulky, but you can still massage while doing housework. This item costs nearly 20,000 yen. Are you suffering from knee pain or looking to do something about cold knees in the winter? How about it? (^ ^) #KneePain #Swelling #KneeCare
