I purchased the SMOK X FORCE a couple of weeks ago and experienced what I call the order from hell. I won't get into specifics but here is the problem. The unit came with 2 coils. A .6 and a 1.2. After priming the first coil per the manufacturer's advice. The first few hits were awesome then after about half an hour I got nothing but burnt taste. I switched coils and the same thing happened. I purchased more coils and the same exact thing is happening with them. Does anyone have these same problems? I can't imagine that I am the only one experiencing this. Any help would be greatly appreciated.
