I have the PT2 minis and love them. I dislike the bigger tanks, because I am always working outside an it is too bulky for carrying in my pocket.
I've been a fan of the protanks & minis since I got mine. Haven't had any issues outside of the norm at all. I was talking with the guy at the shop last night about mods, RDAs and such, just picking his brain...... expanding my own. He did say that when I felt ready to move on, he'd probably recommend the genesis first. He's really helpful..... till someone with a mod walks in, lol. Then he goes all "SQUIRREL!!" on me. I get it.
Yes plastic. What objection do you have against plastic other than thinking glass and metal are better materials so therefore protanks must be better?
