Now I think that I satisfied all people. GGTS has all the functions we need from an e-cig (VV is missing but not for too long) and now we have all the things we need from an atomizer. Rebuildable, takes all atomizers in the market, its a maxi tank, mini tank, small for dripping, works inside UFS. What else we can do for an atomizer? Only to remove the wick from inside. This will be done soon (I hope)
