Looked at the IPV5's, looked at SMOK II, and Cuboid...............IPV5 cheap case (carry mine in pouch around neck...swing BAAANNG on wall..cry me a river broken mod) also heard lots bad about Pioneer and glitches, SMOK nice solid case, but pouch thing with that Loooonnng fire button=problems, Cuboid, solid case, 200 watts all the major wires, compact AND fits my case great and not apt to cause tears if banged around some.......
Went with Cuboid.........only complaint..........it DON'T like my Crown tanks. Due to the massive, squarish 510 pin
(in itself a good thing) and not enough edge relief on top surface
(only issue I've found so far) it and the crowns bottom pin don't like each other. Sometimes shows an atomizer short, sometimes causes TC to go wonky. But careful attachment, snug tighten a tad more than normal and all's good and it hits like a fiend every time and TC works great. A tank with adjustable bottom pin
(or more protruding pin) no problems. I'm a moderate to heavy vaper and a set of 3000 mah 40 amp batteries I go thru 2 tanks...7-8 ml a day (sometimes more

) and still ticking......I'm happy.....
I don't do the max watts anyway, don't need it for the flavor. If I hit 80 w or higher I can't find the door by myself, everyone else helps me out by Throwing me out it!
