Hey Greek, I have the 3ml DC one, and Im really happy you did a vid on the DC, I havnt seen one yet and wanted to maybe chat with you about a issue Im having Ive been useing it at 3.7 and works great most of the time but it seems at a 1/4 full it gets gurlys and dosent vape well like hot as hell with no vape, till I undo it and blow gentle to a paper towel, just seeing if you ran and maybe had a better way to fix that, all in all I love it and just ordered a 5v kazoo just for this. thanks on any info you can give
