If he's ever thinking of getting a russian or kayfun let him know the fogger v4 is legit... its a dual coil RTA so it will be slightly more difficult to build than either but its so much better.
I don't know if it'd be good with an mvp 2.0 though. Hed have to use 32gauge wire and aim for like 1.5ohm resistance, then vape it at the max 11watts.
Any mechanical device though at about 0.5-0.9ohm ... a dozen times yes.
