All the dedicated water containers I have purchased have failed, often fairly quickly. Usually the problem has been with the cap or fancy spigot provided. The one exception has been Platypus, which flatten nicely for storage. Recycled plastic pop bottles are far more dependable. I prefer Gatorade 32 oz. because the mouth is fairly wide. The last time I shopped they were only 88 cents on sale, prefilled with some mildly pleasant fluid that did not contaminate the bottle for further use.
