I should read up on this. He said to attach the mount and let it set up for a day or so before using. I would hate to go riding and get somewhere and have it gone.
i have never had one unstick. i did overtighten and haveem break cause of that tho. so dont go crazy and use a ascrew driver or pliers over tightening the screws.
personally i think making the mount of some sort for the front mouth part is the best place on a helmet
