The handle makes this so much easier to carry than my old tumbler, and it actually fits in my car's cupholder without wobbling. Ice was still rattling around after a full afternoon in the sun, and no condensation ring on my desk.

Didn't expect the tapered base to fit my car's cupholder so well, but it slides right in. The two straws are a nice touch too, I keep the clear one in my bag as a backup.

Took this on a 3-hour drive and it fit my cupholder perfectly, no wobbling at all. The lid hasn't leaked a drop even when I tossed it in my bag sideways, and it's still ice cold hours later. Having two straws included is a small thing but I actually used the clear one for my smoothie.
