Why does the customer have to fiddle with it though? Why doesn't the manufacturer make it so that it works to begin with?
The vortex leaks like a sieve and has incredible wicking problems...you'll have juice in the center tube by the 2nd fill...and you'll get a bunch of juice in your mouth as well. Good luck.
Totally agree we shouldn't have to fiddle but I have to fiddle with poly filled cartos too. I went through those so fast I would go broke if I stuck with them. I couldn't get them to last more than 24 hours. Either they don't wick my juice fast enough and burn or the draw gets so tight it is impossible to vape. I found that the fluxomisers with a 2 minute mod vape great. Once a week rinse out and dry burn they will last a month.
As for the visions I haven't used them due to the bad reviews but GV just released a new version. I am going to order a couple to try out.
