Just bought a Penny mod yesterday. At first it worked just fine. I'm using a magma paradigm rda and I adjusted the posts so that it takes a full push it fire. I had it in safety mode sitting beside me and I heard it fire. I immediately took the battery out, tried adjusting the posts again in slight increments so that it barely makes contact when the button is pushed. Same thing. It started firing in safety mode. Now I'm afraid to use it. Any suggestions? Thanks.
