I had done some research and found these at Lil' Monkey cheeks, as other places are hard to order from. The product itself is as expected, easy to use once you figure out what zipper you need (the company is helpful if you have questions). It is good quality. I had a hard time finding a good place to purchase the zippers from, but Lil' Monkey Cheeks made picking the zippers I wanted so easy (other stores were far more complicated). I got emails about the progress of my order and it was delivered quickly. When I got it I realized I had made a mistake and ordered the wrong one, and Renee made the super easy switch, and covered shipping the new product.
Overall, zippers and insert great, Renee is awesome!
