Dam Frog in the fog screwed up my order and sent me UD Goblin instead of Goliath. It was too much hassle to ship it back, so I accepted their offer to keep that Goblin for $7.00. Not a bad deal? Today it arrived. It has become a habit of mine to look for ways to improve every new device I get. Besides, if I screw it up, it is only $7.00. I decided to install extended air tubes on the deck. You know, to prevent leaking... I drilled the exciting 3.0mm hole to 3.2mm half way into the base. Then I turned new air tubes 3.25mm OD and 2.9mm ID, that's 0.175mm wall thickness. Like hypodermic needles and pressed them into the holes in my deck. Then I made a 0.5Ω build of Tempered 28 Gauge Ni200, 10 wraps 2.5mm ID. Man, this is one crowded build deck. Fogger is a football field comparing to Goblin.
Long story - short, it works on my Yihi SX Mini M-Class, but I don't ever want to rebuild it again this way. The threads in the Chimney well were like a saw blade, I had to use a sand paper to smooth them out and I had to cut some of the chimney cap, because it was shorting to my build.
Overall: Goblin is not my favorite tank.
Will see how is the Goliath, when it arrives. How is yours?
Nice deal on the goblin, heh. I would be happy with it for $7.
Well, thus far I like it overall. I tried a 26g kanthal build, and right now I have a 28g ni200 build in it. I really hate bottom fill ports, so I like being able to fill it without a screwdriver. Its not as convenient as top fill, but the juice control works and is easy to fill the tank even will dropper style bottles. The refilling process is not terrible as long as you don't jank up your build putting the tank back on. The two post design definitely makes it easier to center your build.
Things I don't like about it are the build deck is tiny, even smaller than the goblin, which I already thought was small. The air intake, and holes on the deck are smaller than the goblin, but the chimney is larger, so the airflow is still good overall, but it seems like they missed an opportunity. It runs through juice like any airy dual coil tank, but only has a 3ml capacity. That part doesn't bother me too much because refilling isn't terrible.
My nickel build is dual 28g annealed ni200 3/32 ID, 11 wraps, came out to .072 on my ohm meter, and reads .08 on the SX mini.
Next time I think I may try contact ni200 coils just because the deck is so small, see how the m class does with them.

Seems to be working well around 420F.
