VerifiedGood bottle with a superb cap. It has a sufficiently large opening so you can clean it properly with a dish brush. The cap/lid is great and seals tightly. You don't need to tighten it at all for it to stay sealed. I haven't dropped it on the floor yet, but the material feels good and it might withstand being dropped onto tile a few times
