"I just wanted to give you some feedback on your ice packs. I'm a plastic surgeon and find your ice packs wonderful for post procedure use. I found you on the internet and asked for some samples. I received them promptly and was very impressed with their ease of use and rapid freezing. In addition they last longer than most gel packs that I have used. Their cooling ability, ease of storage and low cost make them the ideal choice for my practice. Thanks!"
