I also have the packaging on the right side, however my authenticity code checks out "authentic" on wotofo site, however I feel like it's not authentic because I don't get any flavor out of the damn think like people rave about. How can I have wotofo send me a replacement? lol seriously though
Many things contribute to "flavor". Size of the coil, position of the coil in relation to the air holes, resistance of the coil, power applied to the coil, type of coil (normal, clapton, etc.), too much or not enough wicking in the coil, how open/closed you have the airflow, thickness and flavor of the
juice, and more.
Personally I have a 4mm diameter coil of 26ga round SS316L (0.58 Ohms) in there with about a 10-12mm wide strip of Japanese cotton, positioned as low as possible, on a HCigar VT75 D mod using TC 25W/435F,
vaping 65PG/35VG DIY Cool Wintergreen Juice and it's perfect. Of course if you change ANY of those parameters the quality of vape will change, and other things will have to also change to compensate. For any and all tanks it is a balancing act of getting all the parameters configured right...FOR YOU.
It is my personal opinion that as long as the air flow of a tank (ANY tank) can be adjusted so you can get the right tightness of draw, it is possible to adjust all of the other parameters to get a good vape you will enjoy. It just takes some trial and error to find it. It took me 3 or 4 builds to get this one right. It may take you more tries or less tries to find what you like. There is no tank that is going to be perfect with every possible build in it.
