Expert Reviews


What reviewers liked

Sweat-free design. All-day performance. Two steel straws.
Top notch insulation. Two steel straws and cleaning brush included.
It did come with a regular metal straw, a thick metal milkshake straw, as well as a cleaner brush, to its credit.
- Wired

What reviewers didn't like

Bulky design. Unknown warming time.
Didn't fit in narrower cupholders. Lid pops off easily.
But the rubber seal around the lid is thin and easily comes out of place.
