This is an amazing massager! I am addicted to it. I have been using it on my back for relaxation, but mainly on my feet and calves due to a previous foot surgery that has left me with some tight muscles and tendons. It really works. Also I sleep like a baby these days! Absolutely amazing, I would recommend it to anyone. Yes it’s expensive but you get what you pay for. Also it feels like real hands! So relaxing and great. I’ve only had it for a week or so but I’ve used it every day and have noticed an improvement already in my sleep and my tight calves.
