Review on AOZEX 64 oz Stainless Steel Water Bottle - Half Gallon, Double Wall Vacuum Insulated with 2 Leakproof Lids - Keep Drinks Cold for 24 Hrs/Hot for 12 Hrs! by Joe Michels

I like this bottle. It keeps my water cold. The only issue I have is the two lids that come with it. The original cover can only be removed if the plastic ring is cut off. It's hard plastic, not rubber. So you may have provided it in case the lid breaks. A hinged lid with a smaller drinking hole would also be nice. When you're drinking from a half-gallon pitcher, it's harder to drink on the go with a mouth that big.
