I LOVE this water bottle! I have been searching for one like it for some time. I like my water to be really cold. Unfortunately, I don't have a big enough fridge at work to keep a large bottle in. I have a Tervis and a Camelbak bottle, and love them both, but my ice is melted in them by lunchtime. I filled this thing with ice, and it lasted all day. There was ice in the bottle after I finished my last serving before bed, and the ice still wasn't completely melted by the next morning. I also had it fall off a 6 foot + high file cabinet onto a tile floor. Small Nick in the lid. That's it. I have already recommended this to friends and family, who will also be investing in one for themselves.
