6V vaping is great, assuming you've got a decent atomizer around 3 to 3.5 ohms

I made a mistake of using a 1.5 ohm atomizer in my GG at 6V one time (forgot to change out the atomizer in the tank) and the flavor disappeared, the throat hit can kill an elephant

and the heat was like inhaling hot alcohol

. 6V rocks, and a set of batteries last about 7 or 8 hours for me. The next thing I'm gonna try is using 2 units of IMR 18350 3.7 for 7.4 volts with a XHV atomizer at around 4.5 to 5.2 ohm, but not available locally....gotta find some from overseas vendors.
However.....I don't think it's that much different if you use a decent 1.5 to 2 ohm LR atomizer with an IMR 3.7V 18650. The only difference I can say, is that 6V tends to be a bit richer in the flavor, but just a tiny bit.
And yes....I know what an Alienware is....hehe.....my ex-gf works for Dell Taiwan, in charge of notebooks marketing. I hear enough about these things.
