I prefer mechs over most regs, because they are just simply elegant. As long as there is juice in the batt and the atomizer, it will vape. Regs, well, they break, they are susceptible to juice leaking into circuits, can short out, and for the good ones, have to wait, usually do a pre-order to get them.
Had a great high amp regulated, loved it, but it broke/defective, had to send it in for repair, waiting on the raptor, this never happens with a mech.
Your Vamo, while a decent entry level apv, is well, limited, can only put out 15 watts, that's it. With a mech, I can vape at whatever level I build for, typically 45-100 watts, depending on the atomizer built. Sure, have to be a bit more skilful, and know my chit, but nothing regulated can match the sheer elegance of a mech and quality rba.
Way I look at it, something like a V5 doesn't do much, heck even the dna30's don't do much more, and is limited to 30 watts, where's the fun in that??
Vape long and Prosper.!!!
