Seeing as how none of it has any kind of real testing behind it.. your fact is as good as mine.
Actually, one of the real values of forums is that they provide consensus opinion. If you read the many posts, you merge the opinions of many individuals into a kind of group-think opinion. And that's what you have here. A poll will be fine, Consumer Reports testing would be fine, but if you read around here you'll see that the consensus is that e-cig batteries do not last a day, certainly not two days. Pipe? Maybe. Cigar? Close, but no. Any e-cig, not even close.
Look forward to the poll.
