Unfortunately, I cannot give it the 5 stars as many others have given here..I found the cheaper, blue ice gel packs work much better, staying colder but most importantly, the gel packs are much more pliable than the ColPac. I had shoulder surgery and needed the ColPac to totally envelop my shoulder AND bicep muscle. The ColPac just does not have the ability to wrap these two areas.Im sure it's great for others, specifically patients that need to ice-up after knee surgery etc.
