Title: New Version is NOT compatible with the old Ventaire-
Review: This new release of Ventaire bottles has one thing to offer- NEW colors. Components such as ends, tops and vents (diaphragm that fits in the bottom) are not able to be used with the old Ventaire system. The new system appears to work as poorly as traditional bottles...nipples collapse, lots of air bubbles/gas. We have a 26 month old and used Ventaire exclusively with wonderful results. Now our on hand supply is dwindling (we have an 8 month old, as well) and we are looking to replace some of our bottles as well as components. Quite a costly venture to have to replace our whole collection!! VERY DISAPPOINTING TWIST ON AN OTHERWISE FABULOUS PRODUCT!
