Chattanooga company makes a few different models of Cold packs. Stick with these (the black ones). They're far superior to the blue ones and will last 10 times longer. The blue ones I bought always developed leaks. I've got Black ones I've been using over a year and this has never happened.I virtually live on these ice packs 24/7 (no exaggeration) for some L4 - L5 herniated discs and have been for about 5 years now so I think I'm qualified to make an objective, trustworthy review. I keep buying these (perhaps every 12 to 18 months). That wouldn't be the case if I weren't completely satisfied with the product. With my terribly bad back, I simply could not imagine life without these cold packs.
