@ander, I was in the same boat recently. My wife needs a vaporizer with relatively uncomplicated controls, as she just doesn't care to figure out anything complex. But, more importantly, it must require no technique with regard to draw strength, speed, length, etc. Considering this, I purchased a Boundless CFX. Admittedly, price came into play as well (I paid $160)
@little maggie mentioned the fact that the CFX is rather new, therefore not fully tested in the real world, so there is that. I've had mine only 4 days, so I don't have much to go on, but I can say that it's very easy to use. Proof of that is my wife likes it and doesn't need me coaching her every time she vapes.
If you're willing to spend more, you could go with a Mighty (about $400), but I was a bit leery about the seemingly high rate of failures (a friend is on his 5th unit in about 15 months). It could be, however, that they've improved upon it recently, as some have reported receiving a newer version.
Oh, and you'll notice I mentioned only portables. That's because I don't see a need for another plugin; it ties one to a particular location (we're both just too restless for that), and I have one I'm happy with anyway. Besides, it's great to have a portable to take to bed at night, just in case we wake up and can't get back to sleep.
