@davehutsell, I never had a video. The wand was waved around way back in my throat, teeth and all inside my cheek area for ten minutes in the morning before treatment. I would do it again in the evening too. Did it work? I honestly cannot say for sure. There are people who have not used the light, and after many years they have no ability to eat, drink and/or speak. It is very heartbreaking. Best wishes to you.
