however, i did read ahead of time that leaking is much less likely if you make sure your ego-t is lying *flat* whenever not in use...in other words, don't lay it down at an angle (such as one would with an analog in an ashtray), and don't put it in a pocket, purse, briefcase, etc. vertically.
I just wanted to chime in with my 2 cents on this subject.
I will start by saying that I ALWAYS leave my tank system vertical with the mouth piece facing up.
If it is in my pocket, it is mouthpiece up, if it is on my desk, always standing up with mouthpiece in air.
I have found, and if you do some experiments maybe you will too, that the surface tension of the juice at the hole keeps it in place quite well.
If you have a half full tank and set it sideways, you can literally watch the juice dump out the hole, where if the tank is full the surface tension will keep it in the tank, because the juice is fully covering the hole.
(I hope that makes sense)
I have had my ego-t (tornado tank, also have a Cignot ego-t low resistance atty as well) for a little over a month.
I have been running 3 attys at once since day one, I like to have 2 flavours on me at any given time, and a third at a different strength that I cycle to sometimes.
I have run everything from 100% PG juices, to 100% VG juices, and every combo of the two, through the tanks.
I have had ZERO problems with leaking, the closest thing to "leaking" I have had is if I have been vaping on a tank all day, and refill it without wiping down the condensation around the outside of the tank itself, and shove it back in there, the condensation will build up around the tank and some of it may eventually appear on the outside where the tank meets the atty.
I found that simply pulling that tank out once and a while and wiping down the condensation takes care of this well, so when I pop a tank out to check fill level, I give it a quick wipe with a napkin or whatever.
The vapour flows right around the outside of the tank (inside atty cover) which allows it to condense there over time.
I pop my tanks in and out A LOT and have had no ill effects, been using the same tanks since day one.
Always get tons of vapour, tons of flavour, and never a leak, I love it!
And as a side note, the low resistance tank attys are AMAZING, all my future tank atty purchases will be low resistance for sure!
