I bought a pack after using cases of ATN. I have had an issue with the tapes on every one. The tops tapes always pop after less then 20 mins, last time all 4 tapes poped while I was worjing on my car. I know they run large and ordered a medium after getting a sample of both small and medium with no issues. I think I am a size 30 waist as all my jeans are 32 and seem to fit too loose. Is this a sizing issue are is there an issue with the maker?
