It's a good self-massager to have around for those days when I've done a lot of intense labor that involves the hands and wrists... digging and planting, pruning bushes, moving boxes, even hours at the computer. I probably use it once a week or so.
After looking at specifications and reviews of lots of hand massager, I am very happy with the one from Lifepro. It does just what I needed-massage, heat and comfort.
