The lid fits snugly enough that I can toss it in my bag without worrying about leaks, and the straw is a nice touch. I've been using it for iced water all day and the outside never sweats, which is a huge plus for my desk.

The 20oz size is perfect for my daily iced coffee, and the clear straw makes it easy to see the layers. It keeps my drink cold for hours, and the lid snaps on tight enough that I don't worry about spills in my bag.

I was a little worried about hand-washing only, but honestly the stainless steel cleans up so fast that it’s not a hassle at all. The 20oz size fits my car cup holder perfectly, and I’ve used it for both iced coffee and hot tea without any issues.
