These really work, bought for Mexico - beer was just as cold at first sip to last. BONUS just hanging - our resort wouldnt allow glass bottles at pool or beach;they inspected these and allowed my wife and I to drink bottles at beach and pool. Must buy for vacationers to Mexico-Hawaii-hot climate. Great buy for just hanging around the house or camping.

We used it for the first time today and it worked great. It holds more than enough water for my husband, myself and our two dachshunds. The bowl is easy to screw off and on. Plenty of room for both our dogs to drink at the same time. I loved that you can even use the top as a cup so more people can drink at once. All around great bottle!

Unreal!!!! there are some fan favourites I definitely have, service is amazing too. Love everything about them.
