Wow, just got my IK Cannon V2. A little learning curve at first. The 2.5Ohm does not like 5v, but it sure likes 4v. I also over filled it and made it leak a couple of times. Now that I got it dialed in, Wow this thing is amazing. I didn't even know BWB Adirondak tasted like this. My only problem now is, I have a head rush from too much nic, going to have to take a break. I may be switching to dripping, it's so much cleaner and more convenient than maintaining clearos and cartos. Just drip in a few drops and vape.
