She says it works. I think her weight loss has more to do with her getting up off her butt, walking 2-3 miles 5-6 days a week and cutting down on the booze.
But if she thinks the Sensa works for her, then whatever!
I'd say look up reviews online. Like on ShopNBC, and I think QVC sells it too. And on other places to get a good few on how it works.
