Bests & Worsts Reviews from Amazon

The glass bottles themselves are nice and thick. The dimensions good for storing a bunch of them in the fridge next to each other without taking up too much horizontal space, but they will definitely move around in most car cupholders. The real issue with these are the insanely cheap caps. The description says Stainless Steel caps, but what is not mentioned is that there is a plastic piece between the steel and the glass of the bottle that can separate, so now almost all of the bottles I ordered after a few months have caps that spin unless you squeeze down really hard to get the cap off. This is an issue because even when you barely tighten the lid, after you put it in the fridge and it gets cold the plastic on the cap seals even more. I have a hell of a time getting the caps off some of the time because of this ridiculous design flaw. I am currently looking online for different caps.
