I typically use a tobeco velocity mini or a Steam Angel dark horse and they work great on this mod. Reading around I saw a lot of people talking about using 0.5ohm subtank atomizers. I put my playboy vixen on with a. 0.1 ni200 and then a 0.5 kanthol and it instantly fried the coils. The battery in the mod was about a gazillion degrees. I then put my aspire mega on the mod. Worked like a charm. It has a 0.3 coil. Can someone tell me why it killed 2 playboy coils? I'm using a 3000mah 3.7 efest battery. Doesn't make sense. I've only been vaping about 3 months. Help?
