Updated Review: Original cap leaked from the flip part, seller reached out to me immediately and offered a replacement. The replacement arrived quickly and does not leak. I am very happy with this cap now!! I like that i can drink more water from the chug cap and with the push button it's easy to drink water while driving as i know have 1 handed operation (using a 24oz size flask). This is a really convenient cap, highly recommend!

I bought this to replace a lid on the simple modern wide-mouth bottle. The design is solid without too many pieces to keep clean. I think the removal strap a clever solution though I wish it was long enough to wear on my wrist.

Not the best, not the worse. The button broke, I still use it but the button keeps falling off.

The button to release the top takes a little more effort. But other than that it works great.

Works well

I bought one because I really liked all the features. The cap over the spout pops open with just the push of a button rather than having to unscrew that cap like some other lids. That cap is watertight and it is conveniently spring-loaded to swing out of the way while you drink. The spout itself is nice and wide for fast chugging rather than sipping. I prefer the long nylon webbing strap to hold it by over the rubber handles other lids use.

Unfortunately, this leaks when attached to my previously leakproof Bubba Hero bottle. Not a lot, but enough to be bothersome. The funny thing is that it leaks in a very peculiar way. I'll take a drink and it'll be fine, then a few seconds after I put it down, drops start showing up where the lid meets the bottle. The only thing I can guess is that the cap is too tall, so it bottoms out on the threads before the elastomer seal on the underside contacts the rim of the bottle. The threads were never intended to be watertight, and the water needs a few seconds to go around and around until it finally issues from the gap. I'll keep the lid, but I won't buy another, and will just have to remember not to lay it down or put it near anything that can be ruined by water.
