This zipper doesn't work since the very first zip!  It's SUCH a shame because the duvet is beyond gorgeous, it's SUPER soft, and looks incredible on my bed!  But I have to literally feed the zipper in manually every time I zip it closed.  It takes about 10 minutes to hand feed it through there or it'll separate and not close.  If they fixed the zipper on this, I would ABSOLUTELY give it 5 stars because I absolutely love it and it's my new favorite duvet....MINUS THE ZIPPER!!!!
