I've got it a week or so ago. My first genny, so I can't really compare it to anything else.
Feels solid. Smooth threads. Doesn't leak. The
tank is plastic, most likely polycarbonate. The o-rings seem sturdy enough. The drip tip that arrived with it is slightly wobbly, but it's not really noticeable. Other drip tips fit snugly and don't wobble about.
The airhole is a little high, but it's tolerable. It's 1 mm in diameter, though, so the draw might be a bit tight for you. My attempts to drill it out have been unsuccesful so far: the top cap is 2mm thick and made of steel.
The top cap doesn't line up with the wick
perfectly, but some fiddling can fix that.
The wick hole seems 2mm in diameter, maybe more? Haven't found a drill bit that would fit it perfectly, so I couldn't wrap the coils the Petar K method thus far.
The fill hole has a hex screw plug, 1mm or less in diameter: you need a thin needle to refill this thing.
TL;DR: not stellar, but it does the job pretty well. Good for its price.
Anything else specific you'd like to know?
