I started with the pen style batteries and could never imagine "smoking" from a friggin box! Soon tiring of switching out and charging batteries, my research took me to, of all things, the MVP2, one of those friggin boxes! But since it fit the bill of what I was looking for, what the heck, I went for it. And I must admit, I really liked the feel of box, the nice grip for an old guy with tremors. The pen styles were relegated to backups.
Then the Atlantis came along and I just had to give that a try. But then I would need a new unit to put it on, oh, what to do? After some careful debate, I opted for a cylinder, so picked up a ZNA 50 Clouper. Yeah, heavy and large, but for my hands, that is a plus.
So my answer? I like both! I find it nice to switch between the two and give my hands some diversity in the feel.
And after I get my Christmas money/gift certificates, I am going on line and picking me up the Kanger Sub and a new box mod to put it on. Then I( should be good to go for a few weeks before the latest, greatest new vape equipment is announced.
