I've had my atlantis mega for a good 7 months i've had absolutely no problems with it. I broke the glass once and replaced it dropped onto a wood floor when i tried to empty it. Just tonight i was using it regularly no problems then i get home try to use it and my box says check atomizer? its not the coil i know that much so i assumed it was the firing pin. I tried it on my old box and it said the same thing, it's not the box because im using my mad hatter rda for right now. every time i try and pull the pin out slightly so it will read on the pin on the box its pushed back in when i screw it in. Do i need a new firing pin? please help i prefer tanks over rda's very much so and dont want to spend the money on a new tank.
