Bests & Worsts Reviews from Amazon

I received this product today. I was so happy it was delivered within three days without prime. As I learned from the reviews, I started to prepare the inserts by wash it with water. I haven't try these diapers on my baby yet. So I don't know if it works great or not. After I soaked the inserts in water, I saw some yellowish color on one piece. Was I received used ones? No, it is some rust. Then I found there was something hard inside. It feels like a hair pin. I had to cut a small hole to get it out. It was a piece of steel with one point very sharp! Thank goodness I found it before I put it on my baby. Because the insert is somewhat thick, it is hard to find the steel piece when it was dry! I guess it may may some debris from manufacture machines. But it definitely should be filtered out instead of shipped to customer. The diapers looks cute, but unfortunately I can only give one star for bad quality control.
