Has anyone tried these. they say that they are better for colic/ reflux symptoms than the Ventair, Avent and Dr. Browns.

Never used them, sorry... I havent heard of anyone else using them... I use Dr Browns.

I hope someone has some experience with them and can give you some advice! :)

We started off using them but I found them quite hard to put together and they ended up leaking a lot. Went to Dr Browns and have found these to be good.

Never even heard of them?? I used the playtex nursers and loved them!!!

I have never heard of them either. We use Dr. Brown's and love them as well.

Never heard of them either. We've used only Avent 4oz-ers with great success (and still use them!)
