I set up my new mod two days ago. A SMPL original, mated to a thundercloud cloud champ rda, running .16 ohm, on a 2500 mah, 35a draw battery. Holy... crap. I'm absolutely amazed by this combo. Of course, I won't be saving a cent. At about 12 ml a day, I'm going to be buying a lot of juice. vaping just got fun again!
