I've been very happy with this tumbler. I actually use it mostly as a water bottle on my desk at work. It keeps my water icy cold for many hours, even without the screwtop handle lid on it. But I love having the screwtop lid with the handle so it's easy to carry by the handle if I need to take it with me somewhere else in my office. I also like that it has a textured finish on the outside, which makes it feel "grippy" when I hold it and I'm not worried about it slipping from my grasp. I wish it had the Cairn Coffee Roasters logo on both sides of the tumbler, but I fixed that by adding a Cairn Coffee Roasters sticker to the blank side, so matter which side of the tumber is facing out, my coworkers can know how much I love Cairn Coffee! It's also super easy to clean, which is an added bonus!
