The spill-resistant straw lid is the real win here — I tossed it in my bag sideways and didn't end up with a single drop on my stuff. Also fits my car's cup holder without wobbling, which my old tumbler never did.

Kept my iced coffee cold through a whole morning of errands, which never happens with my other cups. It slides into my car's cup holder without wobbling, and the straw lid hasn't dripped once.

The spill-resistant straw lid actually holds up — I tossed it in my bag sideways and didn't get a single drop on my laptop. Still had ice rattling around in it after a four-hour drive.
