I feel like vaping on a mech is a pleasure, tho it is convenient to use a box mod, dna, fsk etc. mechs for life!Kinda' funny how even the older well made mech's are still applicable today and continue to provide a superb vaping experience, right? I have some DNAs; DNA20's, DNA30's, DNA40's that aren't anything but ohm readers. But never mechs. Mechs forever!
