Leaford is mostly likely right, very hard if at all possible to do something like this.. First off you would have to
buy all the e-cigs out there, or if you are lucky have free samples mailed to you, then you would have to vap, vap, vap, vap, vap, vap...... We would also need to come up with a Balanced Worksheet by which all the ecigs would have to pass or fail with.. perhaps we can do this with like the top 10 most popular bought ones?> We would need research on which 10 are the most often bought not just from members on this site but in general.
PS - i am super surprised no one went with the screename DarthVapor LOL
