Power scratches!

Hi, I bought this product in January 2011. Shipping and packaging were fine. The processing and the design were absolutely ok for the price, I thought at first. Now, I have agreed to Bumper once a few days ago and had to realize that such brilliant points or scratches caused by the Car under. The plastic in the inside of the bumper has everywhere in the places black stress marks, where the scratches are in the iPhone frame. There was no dust or dirt! The plastic, I suspect, is just not just genung and thus poorly finished. Very annoying for a product that is designed to protect your investment! Not recommendable!
