Review on Shock Doctor Guard Convertible Mouthguard by Jerome Pritchard

This mouthpiece was decent there was nothing supernatural in it what can I say I cooked for a form fitting shape and put it in my kid's mouth about after 10 or 12 exercises it started to peel off. So my son came to the sidelines and took out his mouthpiece and he had little gummy bits in his mouth, I don't know what I did wrong, maybe I cooked it too many times to try it on but in the end I had to have one buy another mouthpiece, i found an old school mouthpiece that us old boys used for two bucks with what we were in high school that has a protective lip that actually moves up and down on the rubber band because the protective lip doesn't move , it is fixed in one position.
