a couple of versions of this idea around lately, very nice looking
something about having to contact a company through email to order always bugs me. and no resellers yet. if this idea interests you check out a company called aerovapes making a big opening splash with everything from mechs to vw to drippers and genis. even a Ti bottom feeder coming!
how about not only a touch sensor but a motion sensor? not even having to press anything for a vape.
looks like the Ti model sold out already:
