I'm so flippin angry. I bought some vape gear off of facebook (my first mistake). So I got a Kraken mod and a Hammer mod. Well, the Kraken is unbuildable. And the Hammer mod won't fire. I'm scrapping the Kraken, too much trouble. But how can i get this darned Hammer to fire?! I've tried pulling the pin up, unscrewing the firing pin a bit, different batteries, don't have any other rda's other than my Tobh, so I can't try another tank. Thanks for any suggestions.
