Certified, badged, and standing directly in front of the problem

Coverage begins the moment you look at me and ends when you look away. Terms are simple because there are almost none.
I stand in front of it. Anything that comes through has to walk past me first, which so far nothing has minded doing.
This is the real product. Nothing has been made safer, but you feel considerably better about it, and that counts.
The badge is genuine. It was made for me. Whether it does anything has never been formally established.
Something got through in March. It was a door, and it was being opened normally by somebody who lives here. The shield still cracked. We have not replaced it and I have not mentioned it since.
