This is my own personal idea, only because im a tank user and what tanks i have used have failed including a UFS. Yes i 'Was" a GG fan!
All i can say is ive ran my idea for a Tank by the Provape team. My specs for the tanks is,
Adjustable airflow switch
Adjustable liquid flow switch
Cartomizer/atty tank
Stainless Steel Tube and end caps
3ml-5ml
Styled to match a Provari.
And a Clear notched window to measure the remainder of the juice inside the tank.
Please do not assume this tank will be made, Just a solid idea for a tank i had and wanted to share with my co-workers
Im also working on the plans for the tank
