Picked up a cheap fasttech hobo and it is performing well. Flavor is nothing out of the ordinary, clouds are what you'd expect from a good dripper. No chuff cap type clouds but it is what you would expect. Love the compact look and design and the $10.20 price.
I had to sand some material off the ring to get it to position correctly but other than a minor tweak it is vaping very well. It was lined up with the posts... like 90° off from center.
Good air flow with the side holes, a good match for a regular drip tip. I may open up holes on top of the two side holes to get 4 that are directed at the coil just for giggles. Don't get the position of the upper holes unless you are building quad coils I guess.
They got it right for single coil, upper and lower holes lined up.
Built both vertical and horizontal, leaning towards horizontal as the better option but not a lot of difference between the two. Side post build has worked best, pretty tight in there.
