“I specifically bought this because it was supposed to be able to get cold/frozen and you can use it on your feet while cold. It barely gets cold as it's just plastic. Honestly, a water bottle frozen, rubbed on the bottom of your feet, is better than this. Save your money.”
“Great for massaging rolling under your foot and plantar fascitis. Even better you can use it hot or cold. I don't have a plantar fascitis now but it is better to use these before it comes back and hurts my feet again.It is great for blood circulation and massaging. Perfect contour.”
