These bottles did help with gas for my boys when they were babies but there were so many pieces and it was hard to find replacement pieces in the store.

Playtex is such a dependable brand for moms and babies but these bottles missed the mark for us personally. In my experience they caused too much air flow and then started leaking through the bottom after only 5-7 uses.

This work great but the hard part is having to take them apart to wash and then having to put them back together again. Time consuming for a tired mommy .

I Hated these bottles so much because although they did help my son with colics every time i had to male sure it was put together right because otherwise my son would get soaked in milk.

I have used these bottles with my older kids and they worked great. I liked that it kept air out of the bottles so it was better on their tummies as far as the gas.

I really love these, they helped so much with my son for the air intake and his burping. he took the bottle better and they were so wonderful.

i love it

Used these for my son....terrible!

I love VentAire bottles! I love that I can reuse them without dealing with plastic inserts. I love how you can easily measure the amount of liquid you need. The only bad thing I have to say is they can leak. I've had two bottom rings I had to throw away because they were making the bottle leak. But, I believe they just got worn out from use.

Love these bottles..

good.

We loved them. The only problem is if the bottom isn't in all the way or if it has water in the bottom they will leak a little.

Did not work out for us. Bought the bottles and plastic inserts but made a mess and felt like they were impractical. Have the whole set away and bought Dr. Browns bottles and she used then without a problem. Plus we produced less trash.

Ugh! These were good for my babies making them spit up less, but you have to make sure you get the parts on right and tight otherwise it starts leaking and if your baby is crying and you're in a rush it gets VERY frusterating! Funny thing is- my hubby NEVER had a problem putting them together. Since it DID help my babies I would definaly recommend them (with the word of caution of course!).

these work wonderfully. DO NOT get them too hot on mistake or boil to sanitize. Also mine always seemed to start leaking after a few months, so replace parts before you make that long trip somewhere and run in to trouble! Worth the work and pieces though. Very effective product.
