I have several GS tanks (the 22mm). I use one everyday at home. I don't use the nickel coils that come with them. I use the 1.5 coils. I run them at 15-17 watts with high VG juice. Big enough clouds for me. Great flavor. Air flow is a bit tight but I don't like too much air flow. Never had one leak.
For running around town, I use a clone GS Air MS from fasttech. Mainly because they fit my iStick 20w batteries better. I use the authentic Eleaf 1.5 coils with those because the clone coils are terrible.
Lots to learn in this area to be sure. I wonder though, comparing cigalike vape to e-juice the e-juice i have doesn't taste as well, it basically has this oily flair, possibly olive oil, which i don't like very much. Do u know if that's generic to e-juice or has to do with the vg ratio?
Trying to decide whether to return both aspire batteries at the moment, or replace just one. Would you replace two aspire vv bats will joytech ego be better or similar?
