I've gotten myself off of a pack-a-day cigarette habit I've had for about 16-17 years with the Protank 2. No more smelling like a smokestack, no more yellowing teeth, and best of all no more shortness of breath and cough. I love this build even though it's the only one I've tried so far. The only major drawbacks to this build I've had are having to tilt the thing too often when it is running low on e juice to keep the wick wet, having too much liquid to deal with in the tank, and it's bulky size. With a smaller clearomizer I could use less liquid so I wouldn't have to keep too much in the chamber for less tilting. I could dump and try new liquid blends without wasting too much. I can also carry it around more easily in a smaller foam padded pvc tube homemade case that prevents breakage of the glass and the battery connection joint and that I can paint and decorate. So as far as my options are what is a better idea for a mini? are the mini P2 clones as high quality as the official miniP2? How do these compare to the mini Davide which costs about as much as the clone? I plan on rebuilding the coils myself for whatever I get. Do the mini Davide and the Mini P2 use the same coil heads? I keep hearing that the Davides are too "airy" and fail more easily. So if I go with the Mini P2 clone am I saving 5-7 bucks but compromising on quality?
