It’s hard to tell if it’s closed all the way. The first time I used it I tossed it in my diaper bag only to realize the entire bottle spilled. I had nothing dry for my 6hr event it was awful. Shame on me for not putting it in a place that was upright but I was used to the original lid that s reward on tight abs didn’t leak. I find it very hard to tell if these new lids are open or closed.
