Ok. I am trying to make my decision as far as which Chi-You clone I plan on buying from fast tech to add to my collection. It is down to either the SS version for $27 or the brass one for $24. I have read the reviews and both are pretty high. But I figured I would ask here if there was any significant difference between the 2 in terms of quality, performance, durability, etc? Also, are they made by hcigar? Just wanted to gather more intell before I actually made my purchase. I also have heard some people have problems with them auto firing when using certain 18650 batts. Is that still the case? Any advice or info would be very much appreciated.
