I wish the adaptors came with instructions because it took me a while to figure out how to get it on BUT once I got it figured out, it's worked great!! I have a coat that goes down to my knees so this adaptor brings the coat extender up about 5 inches. As I've gotten bigger, that's been a big help because I don't have to bend as low to get the zipper done up. Also, I've gotten much wider on this pregnancy and having a zipper down to my knees isn't great. Problem solved!
