The twist-in locking straw means I can toss this in my bag without worrying about leaks, and it clicks into place every time. Sipping takes almost no effort thanks to the contoured opening, which I didn't expect to notice but totally do.

The wider straw opening really does make sipping easier, I barely have to pull at all compared to my old cup. The covered straw is a nice touch too since I can toss it in my bag without worrying about drips.

The twist-in locking straw actually stays put, which I didn't realize I needed until I stopped fishing it out mid-sip. Sipping takes way less effort now with the wider opening, and the airflow valve keeps it from getting that annoying suction feeling.
