Superior shield

I just ordered a roll from the bray group and i am really wishing i didnt, put it on a piece of glass to test dropped a few pebbles from standing and every single pebble put a hole in the film causing a bubble. I threw a small pebble overhand at it went throught the film and chipped the glass. Absolutely garbage! Anyone else hqve this issue with bray? Of course when i tell them my results they respond with well it does work. Smh
