Great if you are having gas issues with baby
I'm only rating this as 4 stars just because the bottles do occasionally leak. Thats not that big of a deal with me though, you either fix the seals or in a pinch wrap a burp cloth around the bottle and go. But I really do LOVE these bottles because my daughter has had significantly less gas issues and her burps are not so in tense meaning she is not swallowing as much air. The unique nipple design fits good in her mouth and doesn't pop out of her mouth while feeding like other bottles I have tried. It's also great that they are self sterilizing, which means no bulky sterilizer for the microwave or some separate device that takes up residence on your counter taking up space. Also great is when you are traveling less to carry around just your bottles and what you need to clean them. They sterilize in the microwave per instructions included.
Rating: 4 stars
