Bin for more than 30 years smoke. Have several times tried unsuccessfully to quit. This went on for about 3h well and then I had infinite schmacht. Do this battery, incidentally, comes with 1650mAh, with Kanger Aero Tank BDC Set (incl. Air Control) now for 2 days. It works! I spent the last 1.5 days sweat very strong, it is now returned to zero. But no more Schmachter on a cigarette. Just incredible what one perceives again odors and tastes. So what I'm saying. The battery works! Fast delivery through Amazon Prime, as always.
