I haven't had a chance to post about this or get with cs yet. I got my clearos a week ago along with a 1300 x2 manual. I already had an auto. The draw on the manual is very airy compared to the x2 auto and my 78mm and 65mm regular bats. I believe I know why...
The battery on the right is my x2 auto, and on the left is the manual. The air holes on the manual are significantly larger than the ones on the x2 auto. The holes on the x2 auto and my regular size batteries are all the same size. (Quick aside... My god, I never knew how much lint a paper towel leaves behind. I can't see it with the naked eye, but the camera flash really picked it up.) In addition to the holes being larger, the threads seem to be significantly less defined on the carto connection, which may contribute to air intake as well. The threads on the cone portion of the manual x2 are not allowing the skirt on a clearomizer to seat fully . If you look at the right cone threads you'll see them sharp and straight, while the ones on the left are shallow and curve in toward the body on the top and bottom. Oh, that thing you see sticking up near the center post on the manual is a small piece of carto condom I cut to try to block some of the air flow to tighten the draw a bit.
I'll get with SI's customer service tomorrow, which is awesome btw and I'm sure it will be taken care of. Anyone who has an issue with a battery with a draw that seems too airy, check out the air holes and your carto connection threads. I'm interested to see if this may be the reason.
Now, about those clearomizers I'm about to go broke purchasing more of...well that's for another thread
