I bought a full size Protank2 and I'm starting to hate it already. I have a mini protank2 and a mini protank3 and really like both of them. I bought a full size Protank2 and can't get it to work right at all. I'm using the 1.8ohm coils that came with it. The vapor production is downright terrible, the taste isn't much better. Should I just huck it in the garbage and call it a loss or is there a way to make it function the way I want it to? I've gone up and down through the voltage and wattage and it just blows all the way through. I'm pretty bummed out, I paid 18 bucks for the thing and I'm feeling like I've been taken for a ride.
