Natursutten Anti-Colic 8 oz Glass Baby Bottles with Newborn/Slow Flow Natural Rubber/Latex , 2 pack. Borosilicate glass made in France. Natural rubber made in Italy.

These bottles are made of super thick borosilicate glass. Extremely good quality. One of them was chucked across the room and hit the wall and it didn’t crack or chip at all. I was shocked, I was sure that it broke. The quality is unbelievable. I am using Lifefactory & Dr. Brown nipples with them though, because the nipples that it came with were too slow for my 9 month old. It’s working great with these nipples, the anti colic valve is great at reducing air bubbles. I am using the bibs bottle sleeve with it when I take it outside or when I give it to my baby so that it’s protected. Even though I can’t use the nipples it came with, the bottles are excellent quality with a good anti colic system. Very pleased with them

I love these bottles! I have tried about every glass bottle available and these are my favorite. The nipple is so soft in my baby's mouth but it doesn't collapse. Plus I love that there are natural rubber. The anti colic piece keeps the air out and her gas under control. And the glass is very strong, I have dropped them numerous times, even on cement, and no breaks so far. My one suggestion would be to improve the plastic rings, they do break easily, even when the glass doesn't. I also had a hard time finding replacements since they were out of stock. This has not been a major issue though. I definitely would not let this stop anyone from buying because these really are great bottles, that was the only downside.

Our household loves these bottles! At some point in our plastic bottle lives I realized the plastic bottles had HORRIBLE flavor after a few months (soap, formula, combo...no wonder my daughter didn't want to drink from them); from there I stumbled upon glass bottles and after trying a different brand I settled on these! I have never had a problem with them leaking. We use Dr.Brown nipples. I love the valve system. They CAN break, but the ones we've had break were due to adults dropping them and probably after multiple drops in general. I have never had one break due to my child dropping them; I also only give her bottles before naps in general, so the bottle is A) in a soft place and B) taken away when she is done. We do not leave her in high chairs, or the like, to throw or drop her bottles from high places. Overall I am sold on these bottles and probably will only use these for the rest of my child bearing years (haha)

This bottle is fantastic. I have had to bottle feed my baby since she was 2 weeks old due to tongue and lip ties. I have also had to feed her formula exclusively because of not producing milk. I have tried multiple bottles: Playtex, Kiinde, Mam, Chico, Nuk, and more importantly Dr. Brown's. Out of all of these Dr. Brown's was the best, but definitely still not great. My baby was still in pain and uncomfortable after eating, and I wanted something better. After further researching anti-colic bottles I came across Natursutten bottles, and they have changed everything. My baby still has to burp, but she does not get the painful gas that would last several hours. Her reflux has improved, and she is much more calm and happy after eating. I am not using the nipples it comes with because my baby can't handle faster flow, even the slow ones are too fast for her. She will be able to use them in a few months, though. For now she uses Dr. Brown's nipples, and they work well even with the anti colic valve. I'm so thankful to this company for designing a product that is so simple and much more efficient at reducing air intake during bottle feeding. Also, not having as many complicated parts to wash is a nice perk. They are also durable, I have dropped them in my stainless steel sink a few times on top of each other and they didn't even chip. I don't do that often and have changed how I wash them in the sink because they are glass and glass is breakable, no matter how well it is made. That said, these are definitely worth the price, and as far as I am concerned the best anti-colic bottles money can buy. I now use Natursutten bottles exclusively and will never go back to other brands. If your bottle fed baby struggles with feeding and has difficulty with gas, reflux, etc., please consider these for your little one. I have had so many problems with other bottles causing intense discomfort and pain for my baby, and these have improved her comfort and enjoyment of feeds by 90-99%.

Don't waste your time. I finally found a bottle that helped my baby with her reflux and was less toxic than others, but the nipples need replaced nearly every month and they have been out of stock for literal months. I've reached out to customer service several times in separation and they told me they would be back in stock in October. Well, they're not. Go spend your money elsewhere. There are plenty of other bottles that are non toxic and have similar anti colic design.
