Hope this pix works, though maybe...I'll deny everything.
Since I have so many bottles lying around I thought eh give it a shot.
Unscrew the bottle that came with the JB and put some napkin under the tube if you like to catch any drips.
Carefully work the dropper tip off a 6 ml bottle. I used a vice grip needle nose since it was handy but any plier should work. I'm using the lemon meringue 6 ml sampler from NHaler right now in the JB but 6ml empty bottle should be available at lots of sites, maybe even your at favorite vendors'.
Insert the JB tube into the 6 ml bottle and screw the bottle into the atty housing.
Threading seems to be the same for the Dekang 10 ml bottles as well as 6 ml bottles since the caps seem to be interchangeable among those 2 sizes.
The standard 10 ml bottle is too long for the JB to close the cover. Threading from 15 ml(?) bottles from GP, alternasmokes and electroniccigarettesofhouston are different from the DK 10ml and 6 ml.
A 6 ml bottle will fit into the JB at a slight angle and will touch the battery. No problems with the JB feeder tube sliding into the bottle as long as the dropper tip has been taken off of course.
Too early to say since I haven't been walking around with this temporary set up for too long but I don't notice any leakage from where the bottle connects to the atty housing.
Because the JB does use very little liquid (which is a good thing in not being a hog), I wanted a way to easily switch out liquids for variety.
