Enigma, you may want to look at the Vivi Nova tanks. They are $12 - $13, so the initial cost is higher, but they come with 3 heads (the atomizer part), and you can buy more heads for $2 - $2.50 each, so in the longer run they will be as cheap, if not cheaper than, the clearos. And they hold a lot more juice and don't leak a drop. They are bulkier, though.
I have found the consistency from one clearo to the other to be sorely lacking. Each one seems to have a different draw and different wicking properties. It all points to a severe lack of quality control in the manufacturing process. I guess all this stuff comes from China, and it is certainly made to a price point, so I'm not sure why the inconsistent quality should surprise me.
Sounds reasonable. Size wise doesn't as I don't care if it looks like a cig or not, however I see they are 510 thread. The battery I am using now is a volt 808 thread. Is there any similar products available for an 808 thread? I'd prefer to not buy a 510 thread battery but if need be I will.
