I have plantar faciitis in my foot and decided to try this rather than a tennis ball to get some relief. I am SO glad I got this. I noticed an immediate difference after just using it for a few minutes. Love that it can be warm or cold! It is worth every penny.
Been using it without heating or freezing. Does well to soothe aching feet. Comes with one roller, not two, but it's good to have the other foot on the floor for balance while using this roller.
