If you are looking for a glass baby bottle, I think these are a great option. Sturdy, good quality, and easy to wash. I do agree with the other reviewers that it’s difficult to screw on the lid. (Especially during those night feedings when you are already bleary-eyed and trying to work as quickly as you can!) Once you put together the bottle, however, there’s no leakage and the nipple does not collapse.

I purchased multiple sets of the three pack bottles and separate lids for my baby. I use the bottles for both milk storage in the fridge and bottles. I’m very disappointed that multiple of the jars seem to have threading issues as I cannot get the bottle ring or storage lid to go on straight and this causes leaks and spills. I breastfeed/pump so it was so disheartening to have so much milk spill all over baby. Not sure if I just got a defective pack but with how expensive these bottles are I was hoping for better. The ones that work are fantastic but I’ve had to stop using the ones with issues.

We wanted to love these so much. We wanted to switch from plastic to glass bottles and these seemed the perfect option, especially with only 3 parts to wash. Unfortunately, all of the bottles leak. If the cap isn’t screwed on just right (which is very difficult to do), the bottle leaks. We ordered several bottles because we wanted these to be the ones we used all the time, but it’s really frustrating when it’s the middle of the night, the baby is crying and I can’t the cap on where it doesn’t leak all over my baby. I reached out to customer service and was told someone would reach out to me within 48-72 hours and I still haven’t heard anything.

For the price of the bottle, I would expect a higher quality ring. It is a cheap plastic and difficult to screw on. It also frequently leaks. We have had to use a regular mason jar ring in place of the plastic one. Disappointed for sure.

They’re really great to use when it’s not leaking. It is a little difficult to get the plastic ring on the glass correctly the first try so it leaks but once it is adjusted correctly, the leaking stops.

I like the glass bottle and the nipples are good. But the rings are so hard to get to not leak. I switched to the metal rings to stop the leaking but now I don’t have a lid that works with it. Please make a lid to work with regular metal wings or make better rings.

By far the worse bottles ever, or should I say lids. The plastic lids do not sit even, I contacted them with the issue (they got back to me with tips & still nothing) they just recommend I’d use the mason jar metal lid (yup still no luck, and I followed ALL instructions). So much milk spilled in the times I had these.

I love the concept of this bottle. Especially since I am trying to lower my plastics use, I thought this bottle would be an amazing way to do that. However; the lid is a MAJOR issue. No matter how I close it, the lid is ALWAYS leaking milk out. It ends up wasting so much of my breast milk that I have to consider switching to another bottle because this is not working out. I had my hopes up for this bottle but it’s a bit of a let down. It’s a great concept, but the design flaws really mess it up

I gifted this as part of a baby shower gift. The momma to be already loves them!

These bottles and all accessories are cheaply made and used to take advantage of mother's trying to get the best of their children. Buy these bottles if you want them to break constantly. Great for recycling but that's about it

I like the bottle and nipple! Easy to clean. The lids don’t close completely and the online chat has taken too long to discuss warranty and guarantee. Just bought item so must have come defective because all are like that

I absolutely LOVE these bottles. They don’t make my little one gassy and they are so easy to clean!

We've tried a couple of different bottles (ComoTomo, Lansinoh) and Mason Bottle is by far the favorite for me and my 6 week old. The nipple shape is most like the breast so she latches easily and the slow flow is just right. No coughing, sputtering or drooling like on the other bottles. Also love how easy they are to clean (hello dishwasher!) and that the nipple doesn't collapse. These will definitely grow with our family for many years!

Excited! Baby is due any day now so we’ve been washing and getting everything ready for him, including his mason bottles!! I am so excited to use them for my kiddo! They are so easy to clean, way easier than a typical bottle that is deep and narrow and takes forever to dry!

Great bottles I love this baby bottles. They are very practical and convenient. Easy to clean. You can build your own or buy it all new. It last well after baby grows and you can repurpose them. So no more throwing away baby things. For the future I would like if the cap for the bottle could be made of food grade silicone and that the lid could be made of stainless steel instead of plastic and food grade silicone for storing food (similar to what Pura brand has) Finally, would be nice to have more options of color for the sleeves. With those changes I would keep buying this product long after the baby was done with the bottle. I love mason jars... so I would easily keep buying the sleeves, the mason jars, the stainless steel lids and silicone lid caps, if you had them. Specially if you also had the wide mouth too! Finally, great customer service! 4 stars only because I see space for improving this product even more.

So excited about these! The price is a little high, but the quality is there. Cute, safe, durable, easy to clean! Can't wait to use these for my little one!

Amazing Product These bottles are so easy to clean & are super cute, durable & my infant loves them!!! Best money ever spent.

Haven’t used it yet. Baby is due November 8th. Can’t wait to use them!!

Great product and arrived quickly! Me (and my seven month old) were happy with it :)

My son loves the shape (more like mother's breast) and I love the convenience!

The best baby shower gift! I love giving a sustainable and reliable gift. can't wait to get my own in a few months why my baby comes!

Love the Mason Bottles! I'm so excited to use them with our little one!

great!! little guy loves his mason bottle. he holds them easily (even without the silicone cover ). customer service with a company has been great. I recommend getting at least three of the rings for around the top. our plastic one broke the first time he dropped it.

They are great bottles that my daughter does well drinking from. I only wish the jars had measurements on the side as the silicone sleeves don’t have the most reliable markings on them

Purchased this as a gift for baby shower. It was on mother’s registry. Was happy it arrived on time.

I like everything about it except two things: the bottle cap sometimes needs a little tweaking to click on well (it might not be leak proof) and I wish it came with more than one bottle sleeve. The quality otherwise is great. The nipples are truly slow flow (which I wanted).

I have lots of jars already (we can a lot) but purchased one the the mason bottles and several nipples…well this bottle is my favorite, we need to buy more! The markings so perfectly clear which makes burping at the right time super easy for first time parents. Also it’s great to know exactly how much our child has eaten. We like this product a lot
