Lifefactory LF500004C6 Onyx Pivot Straw Cap, Glass

The mouthpiece pivots weirdly which I couldn't get used to, and felt rather flimsy and cheap. Stopped using it after about a week.

I personally find that this leaks out of the side when I’m trying to drink out of it

Not very functional cap since it leaks a lot.Can’t recommend.

Fit my Lifefactory water bottle. It is a great replacement choice.

This redesigned straw cap is a great improvement over the previous cap. It works better and it doesn't make the kind of whistling noise the old cap would make. The only aspect left to determine is longevity. I haven't had it long enough to comment on that, but so far, so good.

Comprato in sostituzione ad un tappo ormai distrutto dall'uso. Chiude perfettamente, non lascia uscire nemmeno una goccia anche se capovolgi la bottiglia.

Funktioniert einwandfrei

I purchased this lid as a replacement for Lifefactory 16-oz bottle (transparent color, ASIN B0159YS2RY, model #224100). These glass bottles are AWESOME but the original, flip-cap lid has an awkwardly shaped mouthpiece and didn't always seal completely. The silicone cap also did finally develop a hole after 2 years of daily use (always hand-washed). But this updated replacement design (press-cap) has a much more natural mouthpiece that forms a tighter seal. And it fits the 12- and 22-oz bottles as well. I definitely recommend this upgrade to a great product.
