It took just 9 days to get here after confirmation of my payment. So far, this thing is fantastic. It took me just a few minutes to get a coil put together, but I managed to pull some of the wick out of the coil, so it fell apart. User error, for sure. Thinking that maybe I didn't get the coil tight enough, I made another, but wound the wire too tightly around around the screw and broke it. My bad, again. Third time's a charm. Five wraps of the .15mm wire it came with around the 1mm wick it came with gave me about 2.3 ohms. It's vaping nicely at 4 volts on the ego twist I just bought. Definately much better than a standard ego B tank system. I also bought the downgrade kit so I can use a cartridge, but haven't messed wtih it yet. In addition, I bought all the different size wire and wick they offer, so I have plenty of options. So far, the only things I don't like are the legnth (7.5 inches on the 1000mah twist), and that I didn't notice that they sell a cone that would make it look better on an ego battery. I'll follow up with more info as I try everything out.
