Easy to clean
I bought the nipples that go with, i really love how i can putting on any mason jar with the regular mouth opening. I gotbit for my toddler sense she still wants milk and the other bottles would just be a pain to clean.

No Leaking! Happy with my purchase!
Received today and happy with my purchase!Ordered due to original mason jar caps rusting! I had ordered without reading the reviews first, which pretty much all say that they break easy, leaked every where and that they were not compatible with the COMOTOMO nipples. I was bummed as delivery day was next day (today) and had also read that they didn’t refund… thought I had just spent almost $30 for these caps as I had bought to sera, for them not to work out as I hoped!Honest review : They WERE compatible with my COMOTOMO nipples and they DID NOT leak which I am so relieved! I’m currently using the 4 oz mason jars for my newborn. You do have to tighten the cap otherwise it WILL INDEED leak. So as of today, Im honestly happy with my purchase.

Not Sturdy. Breaks into sharp small pieces.
I wanted to love these, as metal rings can rust. I hand washed them and never put them in the dishwasher. They slowly started to break along this very thin rim around the top into these tiny little shards. Once it starts, it just continues. I was so thankful our 1 yr old never put them in her mouth. If the these were made thicker or removed that thin ring in their design, I would happily use them and recommend them. But as of right now, these are kind of a hazard.

Works as it’s supposed to
So far so good. I use these with the Comotomo brand nipples. I did order Mason Bottle brand but found them way too short for my breastfed baby. The rings work great though! Just wish they sold the tops separate to add on /:

Works fine. Hard to put on tight enough to avoid leaks.
Works fine if you put it on perfectly. Otherwise they leak. It was difficult for my mom to get them tight enough. Ended up using traditional metal rings from canning jars.

Great system - do not recommend with same brand nipples though
These attach as expected to the Mason Bottle brand glass bottles and do not leak from there. However, they do not fit correctly with the nipples so I recommend using with Boon or Como Tomo brand nipples.

If you are debating using the metal rings go ahead and buy these
When I first got the mason bottles I decided I was going to be totally fine to use the metal rings and wouldn't spend the extra money to buy these. The metal ones start to rust super fast especially if they accidentally get tossed into the dishwasher. Metal ones are also practically IMPOSSIBLE to get off if you forget to clean out your bottle basically immediately. These plastic ones are sooo much better. Yes, it is another accessory to buy than just the bottle nipples, but they make the process of using mason bottles much easier and they do great in the dishwasher.
