We love ours!
My wife came home from REI with the red one. I usually dont care too much for tumblers but after trying hers a few times I really liked the 20oz size, the feel in my hand, and the way it functioned. These were still on sale 25% off, so a day later, I went and got the green one. My wife loves hers. She says she has been drinking more water lately now because of the easy access 360° drinking lid. And I absolutely love mine too. I take it everywhere. Hopefully the convenient function of the lid lasts for many years. I've heard a couple of complaints that you can’t take big sips and that the opening is loud when opening and closing. But im not really sure why those would be complaints unless maybe you drink like a camel or are trying to take a drink while caught quietly trapped in a closet in the middle of having an affair or something.
Cold Water All Day!
Unique bottle design allows you to drink from any portion of the top lid without removing it. While a little louder for some the bottle seals or opens with a click of the top, making it very easy to one hand this bottle. I love that the bottle can keep liquids cold all day!
Had to return
You can’t take big sips with this bottle, it makes no sense. If you tilt back to get more than a trickle out it spills all over you. The opening mechanism is also very loud to press when opening and closing.
