Purchased the Belly Extender, the fleece liner, and the zip adapter for my wife. She has a Nobis parka. The adapter that was recommended to us fit onto the parka perfectly. Simple to assemble. Overall great product!
The adapter works for the most part but sometimes the zipper sticks and the glide is not smooth when you put it on, but I guess once you put it on once you don't have to use the adapter zipper. Also, the adapter can't be used as a temporary extender by itself because for some reason the middle "normal" zipper doesn't fit together (even though they are compatible with the MakeMyBellyFit extender zipper).
With the V5 adapter, I am able to use the expander on my long down jacket - perfect for keeping us warm this winter! And it fits on several of my husband's coats, so no matter who's carrying the baby, we can all be warm! This makes so much more sense than just buying one really expensive maternity jacket.
Fits nice - keeps my belly warm
