Picked up 3; all three would short right away with the chamber reducer installed. Going to have to grind away a bit of the inside radius of the reducers, near the bottom.
Aside from that: on two of mine, the positive screws won't tighten down far enough - going to have to either cut them down or find the correct bottoming tap and corresponding drill to make 'em work.
Aside from that: the positive post's outer diameter (it appears to be copper, btw; nice) is perhaps .5mm to large for comfort - knocking it a hair one way or the other and it could short (tested this, there's enough give in the appears-to-be-silicone grommet around the post to let this happen. Going to have to grind that down, too.
Aside from that: it's well built =) I know that sounds sarcastic, but it actually is - all the fixes are easy enough, and what you're left over with is a nicely built rba. The top cap fits snuggly, the build area is a bit compact but perfect for its purpose, the wick holes are generously sized in comparison to some (didn't measure, but the allen keys I wrap coils on (works for me, whatever), I was able to go up a size for the fill hole than what I have to use in some other genny's. It's not 5/32", but it's probably a full 1/8".). And, it's a compact atty - shorter by a good bit than my richman while having a similar capacity (about 2.8ml, via syringe measurement), and reasonably attractive in a simple/clean way.
