Not the best, not the worst

These bottles were on sale for a very affordable price, which is the upside. The downside: they leak like crazy, and even with the vent, still caused a great amount of gas build-up in my little guy. Would not buy again.

very good

This bottles are great used this with 2 of my kids and they wore great l. The con is there are more parts to clean other than that they are good I really recommend Dr. Brown baby bottles.

Great for colic !

My son had acid reflux and colic. We tried alot if bottles. These are the only ones that helped him. He finally could eat without too much gas and acid coming up.

Heard great things about these bottles until I used them for myself. Main issue I had is there's too many parts involved, at least 4 different parts to wash for each bottle. As a busy mom, I didn't have time for that. Also the necks of the bottles are VERY narrow, almost to the point you can't hand wash them.
BUT the good thing about these was the anti colic system, it worked very well for my sons reflux
After trying these, I switched to Tommee Tippee bottles and I'm thrilled.
Sadly I would not recommend Dr Brown's bottles
