I just got my new IBTanked 25mm XL in the mail today. Nobody said this thing would weigh a ton! I guess that means sturdy built though. Now I can vape my citrus juices without worrying about cracked tanks. It sure makes my Twist look puny! No problem, as I got it to go with a bigger PV which I should have before too long. I guess now I'll get the 19mm XL tank for my Twist.
