Just picked up an innokin Cool Fire I at my local B&M. Battery size is 18350. Very nice, good quality for $40.00. The threading is clean and smooth, and the button is a nice clicky one. It comes with an Iclear 30B. Feels like a solid pv. These are set at 8.5 watts, so not sure yet about the 2.1Ω head at that setting for me. Actually, just now trying it after letting the wicks soak up some juice, and it seems to be good. So far I'm very pleased.
