The 16 ounce bottles are the largest of their type we could find and have used since day 1, I call them the family size. The only complaint I have ever heard of was the child-proof lids can be a pain in the butt at times, otherwise, believe it or not, to go to a non child proof lid, goes to a differant make of the same identical looking bottle, that cost $1.00 just because it comes with a normal lid and not child proof.
