I love this product. I play tennis and run. I have been using Kooley Cold Pad to help self-manage a tender Achilles Tendon. I believe it has made a positive difference to repairing my tendon with cold therapy. The Kooley pad is much more comfortable than ice on the skin. The injured spot gets cold without the discomfort that often comes with applying ice. I feel safe as I won’t get ice-burn on my skin. It easily stays in place due to the velcro band. I pop it in the freezer ready for my next use. I have also used the Head-band Pad to successfully manage headaches.
