I need some information on this bumper. There is very little information to be found. I ordered a silver one. It's taking a long time to arrive. I love the way it looks. It seems well padded. It's not a knock off. The finish looks good. It's simple to install. The price is right. I learned all this from pictures and text. I don't like knock offs of American or any other countries designs. I would like anyone's impression that has one. Of particular importance is it's effect on reception cellular, wifi, GPS and bluetooth. My instinct is that cell and bluetooth would be impacted but because of the price I thought I would try it. here's a link: http://dx-box.com/ljy-sword-ultra-t...for-apple-iphone-5-with-metal-back-cover.html There are other stores like WOWcase.
