I really want a Hana... that being said I just can't afford to put out 200+ dollars for a mod. I don't expect the China versions to have the temperature protection or be the actual chip. I'm just wondering if they really do what they say will do. Putting out the proper voltage to attain the watts you desire with the toppers you use at different resistance and if it's a flat line signal. I'm guessing there a few versions of the clones floating around and this may vary. So basically what is the best and most consistent clone that offers reverse polarity protection, overdraw protection, and will cut off when the batteries are dead.
