Yo, I'm just wanting to say, as a relatively new person in vaping (even though all I really do is study this amazing invention), for all the other newbies like myself... if you're using a variable voltage/wattage device, USE THE WATTAGE. I'm not sure why, but the power (wattage) adjustment provides a different and MUCH BETTER VAPE... now, novices/experts, why is this?? They should do the same thing, comparatively speaking right?... for the record, I'm running a 2.0 ohm bottom coil at 9.5 volts from a knock off 4ml pro tank on the vamo, and the vape is AMAZING!
