I really really like mine. We did some research and the outside is a supposed to be a polymer (supposedly better than plastic). Just like Blackberry says, it goes very nicely with my FW, my 99, my 66-6, and the two 301s along with the Curvy. My husband got it for me for Christmas - had a card with a picture of it that said it was mine as soon as he could get it. My bobbins for the Curvy fit it and I love the hand-look stitch that it has - experimented with it today and it does look nice. Has some great features like the flower maker (have a young grand-daughter). My husband says it is the best Christmas present he has ever bought me.
