I like this tank, have 2. I am a medium vape kinda guy, so I run it with a 1.8 ohm coil at 20 Watts. The dual adjustable air flow is great. My main problem with this is leakage. The bottom seal once over tightened doesn't seem to recover. An E-vape specialist recommended I use a vape juice with a 90/10 mixture, makes it thicker and less likely to leak. I think I need to find a O-ring replacement for the bottom seal and make this the perfect tank.
I have spoken with a few people at my local B&M and it may seem obvious, but people just twist the tank to remove it from their mod. That motion will also loosen the bottom cap and seal. I always make sure that I am grasping the bottom cap when removing the tank. I have not had any leaking problems.
