My camera was scratched on my original back, so this was a cool and easy replacement.
Easy install but the film that was supposed to be covering the camera, either inside or out, wasnt there. It would be nice to have a bit clearer indication if that film was there, either with a pull tab, or a different color film. It was slightly annoying not being able to figure out if I had got everything or not.
You may not have any film covering the glass as mentioned in the video.
