Buying water by the case is handy, but costly. The only reason we made drinking out of those bottles a regular habit, was that they fit into our car drink holders. Other than that, even when bought on sale, water can be expensive and a hit on anyone's budget, who's trying to watch their disposable cash. We had bought and used Rubbermaid's other water bottles, but they were never designed to fit into a cars drink holders. Too, the initial design did not provide for adequate water consumption, that is, the drinking holes were too small to drink out of and the lids either broke off, or were not a good fit and they leaked. So, we bought two of these newer chug bottles with the snap-down lids in 16 oz and one size up. They don't leak and fit well into the car drink holders. Leave it to you guys to stifle any competition and get it right. One case of bottled water covers the cost of each bottle and now we keep the backups in a Rubbermaid cooler. I know, I know, we have so many Rubbermaid products, it's scary! Competition is out there, but not really, this stuff is made to last!! I suppose there is other manufactures of products 'like' yours, but nothing quite as well made. Enjoy!
