I just cannot get the Stardawg F3 by Useful to germ. Popped 4, tried various methods, scuff, soak, damp paper towel, straight into rooters, even had em warming up sitting on a wifi router (indirectly). Was only able to get 1 out 4 of the Stardawg F2 by Hazeman going. Guess the full on royal rumble won't be going down
