Thank Goodness My youngest daughter had a bad colic and these bottles worked miracles

Shaped for good reason Used similar for my daughter in 93 and usually give as a gift to help ward off colic and ear troubles

I use the VentAire Advance for my son, I've had the same bottles for over a year now and haven't had many problems. I did have a couple of the "vent rings" at the bottom that leaked, I simply threw those out and used the spares in the kit. My biggest complaint is that the measurement markings on the outside of the bottles have all rubbed off, the original VentAire set I have (not Advanced) still has the markings very clearly.

I love these bottles but they are a little pricey and have a lot of pieces to keep track of. Overall I loved them though.

Love these bottles!! They are great to prevent gas and upset stomachs!! The only draw back was cleaning them, as a new mom it is hard taking them completely apart and clean everything, esp if you have more than one child =)

If you dont put the bottom part on correctly they will leak. I found this out right away. But other then that these bottles are great!

Great bottles. Just make sure you get the bottoms on right or they will leak. No fussy babies due to gas over here.

My son is 6 months old and these are the only bottles we have been able to use. I love them. They can be a hassle to clean but the lack of stomach upset and gas make the cleaning worth it. He use to spit up a lot with other bottles we tried and by using these bottles he dosen't spit up anymore after feedings.

I used these with my babies, especially good for colicky babies and babies that swallow a lot of air. Less spit up too. Happy Babies=Happy mommy!

I use these and the drop ins and I don't know if its coinsidence or what but when my child was breastfeeding she had alot of gas, when I switched to formula, I was expecting more gas, since its milk based and it was from a bottle (which everyone knows babys suck in a lot of air). Her gas resolved when I started using these bottle, no more gas drops! I haven't used any other bottle, but I don't think I want try either. Only issue, sometimes leaks at top, but nothing major.

I used these with my daughter. She was premature and the nipple size was perfect for her little mouth. Great bottles!

I used these for my son when he was a baby and he hardely ever had gas. The only down side was the only way I knew the vents had to be replaces was because it started to leak. But better than the rest of the bottles for my child.

used these for my twins as supplemental to nursing. We really liked them and the only problem we ever had was the numbering on the side started to wear off

I have used this bottle for both my daughters. I love that they offer 2 sizes, standard and wide (which we used more for our mostly breastfed baby). It's tilted like no other bottle and is ventilated at the bottom to allow for better air flow. It's a great bottle to use - just make sure you take it completely apart and clean and dry thoroughly or water will build up in the little spaces!!!

These are the bottles we feed my nephew from and I love them! They are great for an older baby that feeds themselves
