Install was super easy, and the product is great. You can't really tell that anything is even on the phone unless you look really hard. It covers the front, back, and sides. Granted it won't do much for drop protection, but that's why I have AppleCare+. This is great for stopping scratches and stuff on your device. I personally hate cases, and I really wouldn't want to cover up the awesome colors of the 5S, so I usually roll case-less. This year I decided to try a skinomi, and I love it.
