I purchased a Nushape device as a Christmas gift for myself. It's lightweight, easy and comfortable to use. I also purchased the power pack to make my experience more portable. That also was a good decision. The multiple applications makes this a smart purchase, since you can apply it or position it for both therapeutic and cosmetic uses. It has become a "go-to" and favorite, and I do not regret indulging on a pricey but valuable and useful wellness tool.
