Leakproof, finally

I've tried straw lids before that always leaked in my bag. This one genuinely doesn't. Fits my Standard Mouth perfectly and flipping it open one-handed is great while driving.

Good lid, straws need trimming

Works great after I cut the straws to size. Slight learning curve with the cut, but the included straws are a nice touch for the price.

My kids' favorite

Bought this to replace a lost lid and my daughters fight over it. Flip-straw is easy for little mouths and it doesn't dribble.

Decent but straw gets chewed

Functions well and doesn't leak, but I'm a straw chewer and it shows wear fast. Extra straws help, so three stars.

Better than the old flip lid

I'm in my 50s and never loved straw bottles, but this converted me. Easy to sip without tipping, doesn't leak in my work bag, and cleaning the straw is simple with a brush. Worth it.
