I had no trouble installing them on my Hero 7 Black. The installation instructions weren't very good so I found a short YouTube video explaining how to use the parts that come with this kit, followed the explanations and these protectors installed with no problems. You must do the same. It's glass, not plastic, so they won't tarnish or scratch. They don't affect your pictures or videos, and they don't reduce the sensitivity of the rear touchscreen. This kit includes two sets of lens and touch screen protectors and everything you need for both applications. Recommended.
