I use clear protector. It comes with 3 pieces and the same stuff invisible makes their shields out of. Because theback and front is plastic, ive made two key scratches and it went through(because the plastic is soft) and now i have a few markes on the device. The protector also is pealing off within a month or two. They say they will give me another one free but i have to pay shipping. Its not good. I wont recommend.
