Just got one of these and it's really good - VERY happy with it. It was also my first attempt at using cotton and making micro-coils. Turned out perfect first time so I'm pretty gobsmacked I have to say as I usually struggle with builds. Basically followed what this guy did his video:
I've got some Virgin Vapors Organic Chocolate Cake going on (100%VG) and it's pretty awesome

THe only real weird thing is my V4 (from Vape N Quit) has a couple of things that are different from all the others I can see online. It doesn't say "v4" next to "Fogger" on the internal chimney and the airflow mechanism is different: rather than a ring that rotates so you line up the hole in teh ring with the hole in the atty body, it has a ring (without any holes) that screws up and down so closing off or opening up the hole in the atty body. I've stuck a couple of pics below so you can see what I mean. No idea why it's different to others online. Any ideas?
