I bought this on a whim a couple of weeks ago. I've been suffering from plantar fasciitis off and on for nearly a year and I've tried everything to get some relief, with varying degrees of success, but none of them have been as effective as this foot roller. I use it at room temp, in sock feet (it's a little uncomfortable and ticklish otherwise) and roll my foot for at least ten minutes twice a day. It has helped so much I kind of can't believe it. I wish I had bought this thing a year ago!
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.
Great size, firm and works wonders! Doesn't slip all over like a bunch of the ball styles do (haven't tried gaiam's foot massage balls)
