Ok, so i was reading alot of posts about regular and mega cartomizers and desided to test them. I used the same juice in both.IMO i think regular cartomizer beats mega because regular carto produses much more vapor and gives warmer vapor and its adds to a flavor. Mega cartos are fit more juce but I have to suck on it to get any a normal amount of vapor and the flavor not that great unlike regular which gives me clouds of vapor without sucking on it hard.
