I made my best attempt at maniacal laughter when I realized my error. 
A couple weeks in for me, and this atomizer is not exactly my favorite. I might need to try the 2.0, as the 1.5 is quite hot for me, and I don't get a ton of vapor. Furthermore, the draw is getting very stiff. Is there a huge difference between the 2.0 and the 1.5? Should I take the plunge?
A lil birdie told me that the next batch will be the more improved revision, stay tuned folks.
Strange. That little birdy is the spokesperson for all vendors of ECF, 'eh? ;-) -Magnus
Is this too high voltage on 2.0 atty?
I would say that 4.2 volts is about as hard as you want to push a 2 ohm atty,and 3.7 volts for a 1.5 ohm atty if you wanna get any kind of life out of them.
Gonna toss this out there for our Int'l vapers. I'm already sending some of these awesome attys to a vaper in Europe. I spoke with John about the high shipping charges and they are working on it. In the mean time, if anyone would like, I am happy to order for you and ship. All I ask is pp payment to order the attys and then pp payment once I know the actual shipping charges. So far it seems to be in the range of $3.50-$5.00 dependent on weight. Also need clear directions for the customs declaration form. Typically I am able to get to the post office 2Xs/week.
tierrataz is a great ECF-er, fsroq, and someone I've dealt with in the past. Go for the offer.
