Amazing product! Great for people with back problems.
First of all it shipped fast and came early. This massager is so amazing and relaxing. It really does get very cold and works really well working out tight muscles. I would highly recommend it. I've never had a massager that felt as good as this one. If you have back problems and it gets so tight you can't move, use this massager, then put on tiger balm after, and it will help astronomically.
I suffer horrific migraines and this somewhat helps when I use. Our sons play Hockey and they love when I use this on their sore muscles after a game .. 10 stars!
