Review (2/5): Foldable is a Great Concept
Easy to use and easy to store are two of the best features this product has going for it. The bubbles are nice as well.
The heating element gets EXTREMELY hot and is easy to brush up against if you have large feet.
The shiatsu rollers are do-it-yourself, so you have to move your feet to get any benefit, again, increasing the likelihood of touching the heating element if you have big feet.
Good idea, but needs a redesign.
