The General Salesmen tactics for this product are usually shove you onto the ground, put it on, tell you it helps, the Placebo effect kicks in, and then... he kinda just shoves you onto the floor again, I could see right through it, I played along, but I wasn't affected, so I returned it and said it doesn't do anything, He said they did, and I was wrong, but I could tell it in his eyes, he totally agreed.
