I have the 24mm Moonshot. It's my favorite flavor and vapor device. It's my least favorite device to build on or wick. Building is a pain, but not so bad. Wicking is where it becomes frustrating as it's sort of a trial and error and cross your fingers sort of affair until you figure it out. This is common with any device, but the particular problem here is, trial and error on this device is a painful process with the wicking as you are going to definitely have a mess on your hands the first couple attempts, or something that is a dry hit machine that's over stuffed.
In any case, when it's wrong, it's kinda a time consuming and messy affair to take everything apart, clean, dry, rewick and try again.
I watched alot of videos on how to wick the Moonshot...and none of them work for me. Here is what I do:
I have 2 2.5mm claptons for a total of .5 ohm. I cut off 2 strips of koh-gen-doh cotton that are slightly wider than the target bore(~3mm?). I then tease the cotton thinner until it is about 5-6mm wide. I pinch and thread one end, clip the pinched end, refluff. I point the cotton upwards and thread the base/wicks through the chamber piece and screw into base. I then cut off any excess cotton so that there is about 2mm of cotton above the chamber piece. Some needlenose, hook calipers are useful here for bending and tucking the wicks into the chamber. Using the needlenose calipers tease some of the cotton out of the side of the wick holes on the chamber. You just want a slight bump and assure there is a cotton seal in those big holes...or else you are going to have lots of problems. Prime your wick material, check fire real quick and assemble unit.
You should be set at this point. The unit WILL flood on fill if you don't close the air intake. On first fill after a fresh wicking, you should let it sit for 15 minutes before you start in on it.
Unit gets very hot, you don't want it flush against your device. Back out your devices 510 pin so there is about 1mm between device and atomizer.
I also find that the device does not work well at the maximum air-intake. 75% is a sweetspot for me, but with the air-intake open all the way there is zero draw and it negatively effects the atomizer imo.
