The tapered base actually fits my car's cupholder, which my old tumbler never did. Ice from my morning coffee is still rattling around at lunch, and the handle makes it easy to grab one-handed.

I've been using this daily for my iced coffee and it genuinely doesn't sweat, so no more wet rings on my desk. The handle makes it easy to grab one-handed, and I like that a second straw came in the box as a backup.

Took this on a hike last weekend and the lid didn't leak a drop in my backpack, even tipped sideways. The two straws are a nice touch — I keep the clear one in and the color-matched one as backup. Handle makes it easy to clip on too.
