I like it alot(what's not to like about free though). Used the two Clapton coils it came with ohming in at .10. Put some 70/30 juice in it and I'm running it at 50 watts. It's a cloud chucker with great flavor. I'd spring for the 29 bucks VaporDna is selling it for. I open the bottom slot 1/4 and the side holes at 1 hole. No leaks yet, easy top fill and holds 5.5ml of juice. After I beat the Clayton's up I want to try some kanthal round wire to see how it handles.
I cut the legs on the coil at 5.5mm, next time I'll go 6mm. Coils had to be forced to sit over the airflow, they needed a pinch more to be all the way centered on the airflow.
