Feeding Classic Glass, Twist Bottles, 4 Oz, 6 Bottles.

These bottles are great! They vent super well and are super easy to clean. I actually bought the 8oz bottles as well. My chief complaint would be that the measurement markers are extremely difficult to read. My daycare requires glass bottles to have a cover. I have found that the Bibs neoprene sleeves fit these bottles but I wish they made a silicone sleeve for these. Dr Browns silicone sleeve would fit but then you cannot read the measurement markers at all because even with a “window” on the sleeve, the markers on these bottles twist with the bottle.

These bottles are simple, sturdy, and reliable! I love that they’re made of glass, so I don’t have to worry about chemicals or lingering odors like with plastic bottles. They clean very easily, either by hand or in the dishwasher, and they don’t stain. The nipples are soft and easy for my baby to latch onto, and I haven’t had issues with leaks.

These are the best glass baby bottles ever. They help babies with no gas buildup and they're good to have

I just got these bottles today but I already love them! I’ve had other glass bottles and they’re so thin and easy to break. These are not too thick but not thin enough to crack easy. They’re the perfect size! My baby loves the nipple on it and that is surprising with a breastfed baby but she seems perfectly happy with it. The anti colic valve in the nipple is great too. You can actually see the air bubbles going back into the bottle instead of my baby’s belly. To compare she was using the Dr. Browns narrow neck with a Preemie nipple. And she does just as good on these. The bottle doesn’t leak. It washes great and is sparkly every time. And for the price you really cannot beat these. I will be back to buy more!

I’ll be honest—these bottles aren’t the prettiest. They look a bit cheap and plain, but don’t let that fool you. They are by far the best-performing bottles I’ve used. I’ve tried Dr. Brown’s, MAM, and the Baba silicone brand, but these outshine them all. They’re incredibly durable (they’ve survived many drops!), easy to clean, and heat up quickly. One feature I love is the ridged design—it helps mix the milk faster with gentle stirring, which is a big plus during late-night feedings. THEY ALSO DONT LEAK!! Like my Dr brown bottles. Another huge benefit is safety: these bottles are free of lead exposure, unlike others that use painted logos or decorations—even the glass ones. My only complaint is about the new lids. They’re smaller and harder to remove with one hand, and unfortunately, they don’t fit the older Evenflo bottles I have. They’re also easier to misplace because of the reduced size. The product photo still shows the older, larger hood, which I personally prefer. Overall, despite a few design changes I don’t love, the quality and safety of these bottles make them a top choice for me.
