I have been trying to get my tugger to work for a couple of days and I cant figure this out at all. If I'm not mistaken there are 3 parts to this device. I've been looking at Supra pics of how he wear the tugger and I cant get the tugger to stay on my head for the life of me. There is supposed to be some kinda of "suction" that keeps it on?? I don't feel anything and it will not stay on. Any kind of help would be appreciated thx.
