I was looking for a compact bottle to fill after airport security and something small enough to fit into my handbag at my destination. It folds up small and as other reviewers have noted the sides of the bottle were kind of stuck together HOWEVER I simply blew into it like a balloon and the walls separated with no problem. The bottle stands upright well full and even with little liquid left inside. I didn’t taste anything from the bottle itself and I am funny about the taste of my water. Fits great in my handbag without taking up much room. It’s not big but holds more than enough to take the edge of being thirsty walking around. I would recommend that you hold the bottle by the plastic rim so the water doesn’t flood out if it when drinking. No leaking so far from the lid so fingers crossed it holds out for my trip.EDIT- I purchased a black bottle for my son because I liked the yellow one so much, and noticed that there was no rubber seal inside the cap. I double checked by filling with dish soap and water and giving a little squeeze and sure enough bubbles formed at the lid and neck. So, before you go out with your new bottle double check the rubber seal is provided in the lid. I returned the bottle and requested a replacement with no issues. The new bottle has a seal.
