I actually have no idea how good this product is since I was sent a $19.99 pair of slippers which I have since returned and still haven't received my refund yet.
Good foot massager for tired and achey feet. I bought this for a white elephant gift exchange. Of the 35 people there, it was the most coveted gift.
This is a good item it works for it's purpose it does not keep water warm and if u turn bubbles on it actually makes water colder faster but it holds the water
