Hi. Here's the deal. I've owned a hammer of god that went dead. Sent it in for repair, got it back, worked for a day, went dead again, threw it away. I've also owned an 11:11 mod, stopped using that because of a hot switch button issue. Silver-plated firing pin afaik on the HOG. Owned a Sub-ohm innovations legendary mech mod with the broken silver-plated needle firing system. It looked like a circle held together with a grommet but broken into pieces. That mod worked for about a year and a half but won't fire now. Call me out if I'm wrong on this. Here's my current issue on a recent purchase I made from Armageddon manuf. one of their mech tubes: BTW, if you're interested check out my Instagram mentioned below to see the mods I have or at least what I've taken pictures of. Here's a copy of the e-mail contact I sent to Armageddon manuf. and the picture I sent them as well. If anyone on ECF has ideas let me know the more heads the better. =) I'm guessing one solution would to be to use sandpaper.
