The tapered base fits perfectly in my car’s cup holder, which is a huge win for my morning commute. Flip lid’s been tossed around in my bag twice and not a single drop leaked.

The double-wall insulation actually works—ice was still clinking around after a two-hour meeting on my desk. Flip lid sealed tight when I tossed it in my bag sideways, and the tapered bottom fit my car's cupholder without wobbling. Two straws in the box was a nice surprise.

Took this to a tailgate and the tapered base dropped right into the cupholder without wobbling, even on bumpy bleachers. The double wall kept my drink ice-cold for the whole game, and the flip lid survived being tossed in my bag without a drop leaking.
