Baby loves these
Switched from Lansinoh (plastic) bottles to these. I primarily nurse my baby but every once in a while we use a bottle. I love that you can use mason jars for it, and he has had no issue with latching afterwards. I feel like the top of it is a great design and promotes a great latch. We have had 0 issues with leaking and everything seems like really great quality

Very practical and helpful to keep fewer plastic bottles.

Finally found a glass bottle that doesn’t leak
I switched from Philips Avent glass bottles to this one and I’m so thankful. I had leaks daily before, now I don’t.

Almost what I want
I have exclusively used these bottles and although its a nice alternative to using plastic bottles there are some downsides. I would 100% recommend using a metal ring instead of the plastic ones. It’s way too easy to miss the grooves to screw on the plastic rings and it leads to severe leakage! Just make sure you keep the metal rings dry immediately after washing or they’ll rust.The other downside (which the brand does warn about if you’re not careful) is cracking in the glass. I briefly stored some milk in the 4oz size in the freezer to test things out. It worked for a little while but eventually the glass did crack and I lost 2 out of 4 of my jars.I love the idea of this style of bottle and I can’t wait for more options like this.

Perfect way to reduce waste
I love that theyâre isnât any plastic touching my babyâs milk. And these bottles are super easy to clean and put together. Iâm not overwhelmed with pieces because the jars are already a staple in my home.

Perfect nipple, enabling a super flexible method for storing milk.
I really liked the idea of having a glass milk storage and consumption setup for my daughter. The mason bottle perfectly enabled that. We stored milk in 4oz mason jars and stashed them in the freezer. Feeding baby at night consisted of thawing a portion in a kiinde kozi bottle warmer, attaching the mason bottle nipple and wham – happily full sleeping baby. We never even used the sleeve thing. Baby liked the vented nipple, which works perfectly, much better than the unvented nipples and bottles that came with the pump. I like that the nipple is simple, it doesn’t have multiple parts to clean like other vented bottles. We are now supplementing with formula, prepared in mason jars since baby is older. This product is excellent, durable and investing in a pack or two of 4 or 8 oz mason jars is super useful now for frozen solid baby food portions.This product is awesome.

Perfect Baby Bottles!
We use mason jars for everything, so this just made sense. I love that I can pour pumped milk into a mason jar, store in the fridge or freezer, warm it up in a bowl of warm water, and serve it – all in the same jar. Plus, they stack easily and there is no waste. In the freezer, I place my jars in a freezer bag.I bought the 4 oz. and 8 oz. kits. Do yourself a favor and buy both kits. Then make sure you’re stocked up on the right jars. I prefer the 8 oz. jars because they are easier to hold and sometimes I pump more than 4 oz. at a time. I breastfeed about half the time and feed with pumped breast milk the other half of the time (so my husband can bond with our little one) and it’s so nice to have 4 nipples and a ton of jars and lids.Our baby loves the nipples. She took to it so quickly on the first try. I do use nipple shields when breastfeeding, which is probably why we can go back and forth so easily.I usually use the turquoise holders to measure pumped milk since my wearable breast pump isn’t always accurate. We rarely use them when feeding our baby, but that will probably change when she starts holding her own bottles.I wash everything in this kit in the dishwasher. I also wash mason jars in the dishwasher but hand wash the metal lids and rings.
