Meets My Overnight Needs

Pros: It holds a lot of water and easily stays cold overnight without ice. It's easy to clean. The handle feels very sturdy. The cap design makes drinking easy without spilling. Pretty teal color! Nice simple design. Cons: Eventually the water starts tasting like the metal of the bottle if the water is in there for too long. It's too big for the cup holders in our van.

This is a replacement for the same cup for the same one that was lost. I knew it worked good so I wanted to have the same cup. It keeps my ice frozen all day.
