Ahh, ok, gotcha.
First off, I hated the iClear16 clearos that came with it. They destroyed the taste of my favorite e-juice. So I went to a local B&M and got a kanger T3S; liked it so much I ordered another. I also got an ARO Pyrex, for the naughty juices that destroy plastic, but that one is like 3.5ml, so as much as I like it, I'm looking for another pyrex with a smaller tank. Seriously considering the Protank II Mini, since I like my plastic kanger tanks so much. I posted a thread asking for opinions of it in the "Clearomizers" sub-forum, but haven't seen anything yet. I may also get other kinds of plastic tanks, but they'll be bottom-coil, for sure. Probably not dual coil, as I find the single-coil kind quite warm enough, and it seems to me that having 2 coils would necessarily make it a lot warmer, which, like the top-coils, would not be too good with my favorite e-juice. I've heard good things about the Evod, so I may look into that; they seem to be affordable.
One other thing -- I found the "retractable" doohicky on the iTaste's USB cable to be a real pain in the ...., since I almost always use my iTaste in "pass-thru" mode, from the USB port on the front of my computer; that plastic gizmo was always banging against the desk, so I started using the USB cable that came with my eRoll, which has the same micro-USB as the iTaste. It's also a little longer than the fully-extended iTaste cable, and seems a lot tougher; the iTaste's cable seems so thin and fragile to me, and I'm a klutz non pareil -- much better for someone like me to use the tougher cable.
When we get our fed refund in May, I'm planning to order a couple more iTaste vvw3 batteries, just to make sure I always have a working PV.

Maybe I'll get one of every color -- the one I have now is the "pearl chrome".
