Cute post.I've got to say though that cartos must have come a looooong way since I last used them, because they were nothing if not consistently inconsistent back then.
Of course, when I was buying them it was those or the atomizers that you had to use coffee stirrers or fluval or pyramid teabags with to get them to work correctly. Needless to say, I went to dripping I was so frustrated. Three. Drops. Every. Few. Minutes.
As for the protanks, I just removed the silicon cap off the center and now get a perfect hit each time with no leaking. *shrug* Funny how each person has a different experience.
I do the same exact thing with my Protanks and they've all been vaping perfecting ever since.
