Please share your tank experience here....i wanna buy 1 more tank.
Tank that i used b4 and i share mine too
Subtank [sold] - Single coil......spiting juice, hot but super easy rebuild. No leak issue.
UD Goblin mini [using 2pcs] - Taste very good but if use sweet juice more sweet on this tank. Good for cold juice. Throat hit and thick smoke tank also. Kecil kecil cili padi

Like it very much. No leak issue.
Taifun GT ll [sold] - Very good taste for single coil tank but it minor leaks at the bottom 510 thread screw.
TFV4 [pending selling] - sux

need to wick nicely if not....leak leak leak. Taste very poor but can hit very wattage without burning smell. Thick smoke. Drink a lot of juice. Big tank.
Billow V2 - Good for daily use. Got taste and smoky also [depend on the coiling ohm]. Good for cold and creamy juice.
Billow V2 nano - Taste better than Billow V2 [maybe the tank shorter]....throat hit also. Tank too small like Goblin goblin....fast out of juice

Same like Billow V2.....good for cold and creamy juice
Topbox nano - Still sleeping inside the box.....havent found the rba yet

. Very slim. Top refill.
OhmMega [sold] - If u like super cold juice this is the right tank. Less taste but smoky. Dripper coiling design. Can build 4 coils on it.
That is my experience on above tank. Hope u all also share your tank experience. Thanks

Your TFV4 experience will improve when you pull the coil higher. Its advisable to have your wick at least 6mm for the juice channel. This tank is big, so does your coil and wick.
