The tapered bottom fits perfectly in my car's cupholder, which is a huge win since most tumblers wobble or don't fit at all. Double wall insulation keeps my coffee hot for hours, and the two straws are a nice backup.

The leakproof flip lid actually works—I tossed it sideways in my bag and not a drop came out. The tapered shape sits perfectly in my car's cup holder, and having two straws means I always have a backup when one gets lost under the seat.

Took this to a tailgate last weekend and the tapered base fit right into the cupholder on my camping chair, which was a pleasant surprise. The double wall insulation kept my drink icy for the full three hours we were out there, and the flip lid held up fine even when the cooler got bumped around.
