i loved this its a great shaker and if you keep it tight it doesn't leak like other products but after using it for a while now the lid pops open on top on its own. there are little groves that keep it closed they seem to be looser now and they slowly slide and pop open. so the lid is useless now worst thing is there doesn't seem to be a option to purchase a replacement for it. i would prefer a different top to be fair i would not want the same pop open top,

I drink smoothies and protein shakes everyday and I wanted something non-plastic. It still has plastic on the top but at least my shakes aren’t sitting in a plastic container as I drink it over an hour or so. It doesn’t leak and the size is right. As a bonus I wasn’t planning for it keeps my drinks colder for way longer than the plastic bottles do.

I know this is intended for shaker beverages, but this is now my favorite water bottle. I love the lid. Perfect size for drinking water that’s not a straw or having to unscrew a lid. Love that the lid stays back when open. And lid isn’t difficult to open like most lids on shaker bottles.

The cap does not stay on. It pops open randomly and the slightest bump or drop opens the cap, spilling all contents. Really bummed on this purchase since I travel with my shaker bottle. It’s virtually unusable for me and I’ve been left with some embarrassing moments with protein shake all over the ground.
