I test flavors just by dripping a few drops on the coil. You can taste for a few hits before it changes to whatever you have in the tank. I just tried licorice and now it's back to papaya. I love papaya. I just hand carry my Zen everywhere, works for me.
I have two main subjects that I would like some advice about.
1) testing flavors. I know zen said something about filling the tank half-way with PG and then dripping on the tip to test new flavors. what do the rest of you do to test?
2) traveling with these devices. How do you all do that most effectively? I mean how do you carry them safely and also so that the juice does not come out? any tips and tricks?
I would like to start to carry these as my everyday device but have been a little nervous about the issues I mentioned.
