Not great

Didnt like these bottles at all. Found baby got way to much air making him have lots of spit up as well as puky. Only reason i had given it a couple stars is the customer service was good.

It's ok.The only thing I don't like about the Playtex Ventaire bottles is that while it's easy to clean,the part that attaches to the bottom of the bottles has tiny holes in it so water/milk leaks even if the cover is on tightly.Easy to wash and clean.If they made the Playtex Ventaire bottles without tiny holes on the bottom cover I would buy it.

My experience with these bottles was less than perfect. My grandson was very unhappy with them as he always seemed to be getting air and/or gas whenever we used them. This went on for several weeks with us wondering why. When I had read another review we switched immediately and problem was solved. Happy grandson back!! I realize many people love these bottles and I am happy they have had success, but if you notice anything different with your child when using them, I suggest trying another bottle. Just to see for yourself.
