The tapered base fits perfectly in my car’s cupholder, and the flip lid seals tight enough that I tossed it in my backpack without a drop. Two straws in the box is a nice touch, and my coffee’s stayed hot through a whole morning of classes.

The tapered base fits perfectly in my car's cup holder, which is a huge win since most tumblers wobble around. Took it to a full day of classes and not a single drop leaked out of the flip lid, even tossed in my backpack.

I dropped it twice in the parking lot and the flip lid didn't pop open once—that leakproof seal is the real deal. The double-wall keeps my coffee hot through a full lecture, and both straws being included means I've got a backup for when I inevitably lose one.
