Well, I just blew the pack in my house. Wife is super pissed at me. Took me a bit to find the release valve. My bag did not deflate until I hit the release valve btw. Good 10-15 minutes and the airbag was still solid full of air. That might not be a good thing that your experienced Shred. Got it all packed back in it's spot. Now I just got to get the cartridge refilled.
