This is really one of the best buys I've made in a long time. It relieves muscle pain, improves tone, and de-stresses. I was really skeptical & couldn't imagine how it would live up to what I've been reading online, especially since this is one of the cheapest models available. It's well made and I'm am so pleased. I had problems with chronic muscle pain and this is the only thing that has helped. It's so refreshing to use. Leaves me feeling clear-headed afterward as well. I don't know if it helps with weight loss, but for toning, it's incredible.
