What a great concept/idea!! I love this. Not only was this appealing so that I could use my expensive coats that I already have- but it followed through on ease of use too. I plan to take walks in the winter through my pregnancy so I knew I needed something WARM. Well most maternity coats are either cheap material, or VERY expensive. And I couldn’t justify spending that much on something I would only wear for one season. Then I found this! Solved all my problems. I could use the normal extender with 2 of my coats, and just had to buy 1 zipper adapter for my 3rd coat. I had a question and they answered me very quickly. Awesome customer service. Product was shipped and received fast as well! When it came, it was easy to use, and it looks great. All around great experience getting this. If you’re on the fence, get it!!
