So basically, you are wanting an over priced, equipment exclusive, one size fits all type of vaporizer. That might work for some, but I would never have quit smoking wih that type of set up. Everyone is different. Different juices work better on different devices and coil configurations. As for ease, this is why I like rebuilding RBAs. For pennies, all I need to do is take the time build a coil or two(to my liking). After that, for months, all it takes is 5 minutes of rewicking and and occasionally a dry burn and I'm done.
