i have both kayfuns and pico..
the brown box not sure from which cloner but the tin one is from sxk, as i have 2 picos, brown box and tin..
flavor wise, with the right setting, the pico will be on par with the kayfun, flavor wise..
for pico, try to get anywhere from 0.5-1.0..
mine is currently at 0.95ohm..
so far, its my daily tank with my kayfun mini v3..
both are sxk clones..
