The twist-in locking straw actually stays put, which is the whole reason I switched from a loose straw I kept losing. The wider opening really does make sipping easier, no effort at all. Only thing I'd want is a lid that's easier to snap on.

I fill this with ice water every morning and it actually keeps me sipping all day thanks to that wider contoured straw opening. The airflow relief valve is a small touch but it makes a real difference, no glugging or struggling to get a drink.

The twist-in locking straw actually stays put, which was my main gripe with other cups. Sipping takes way less effort thanks to the wider contoured opening. Only wish the covered straw were a bit longer, but it's solid for the price.
