great product but DON'T get it WET!
Every time I used this product I was pleased with it. When other people see it, they want to try it on, then they love it and want one for themselves! My hesitation about giving it more stars is that if the cap gets wet, it's ruined! I have never had an ice-pack that could not get wet. The gel inside the cap swells and becomes disfigured and unusable. If you buy one, you'll probably love it, but be VERY careful to protect it from water - put it in a plastic bag to chill it. NEVER put it in a cooler (that's how mine got ruined). I would have loved to use this product for years! The strong cooling effect lasts about 10 minutes, with some lesser effect for another 10-15.
