Okay, so I've been vaping for a couple of months (hollaaa) and I have a itaste VV with a protank 2. the coils I am using are the Kanger 2.2 (I think). so long story short, I went and bought a few more tanks, but this time I just bought the protank mini. when I vaped from them I realized that either A) something is wrong with my protank 2 or B) the protank 2 just plainly sucks. So when I pull on the protank 2 I really have to suck (I hate that word), however, when I vape with the mini it's almost effortlessly. I've changed the coils, re-assembled it, and it's still the same. Is this how everyones is? or do I have a faulty one?
