I've had the Screwdriver (sold it) and the Stick (defective - replacement on the way). I'm on the waiting list for the Prod. The others I've heard good things about, but no personal experience...
I have not vaped anything above 11mg in strength with any of my gear and still get throat hit in abundance....I even have some ultra low (4mg) from puresmoker that got good hit from the stick.
My old reliable right now is the Kissbox/manual switch... and there is a difference - the KB has to have fresh batteries to deliver that punch...once they start to peter out - meh. So I'm continually switching out batteries on my KB - can't wait for the prod!!!
If nothing else, stick to the manual switched gear. You can pre-warm the atty, and that, again, gives you a better punch....plus, bonus, no primer puffs required.
Hopin I helped with this old wall of text.....
