Promising review: "I love this water bottle. This sucker keeps drinks cold and ice cubes solid for hours upon hours. I was truly amazed the first time I used it. And I’m not talking, like, it keeps things slightly cold after hours...it keeps things ice cold for hours. I’ve had this water bottle for over a year now, use it frequently, and it still looks brand new." —EH4
