Leaford you seem like a pretty upfront guy and dont seem affilatiated to anything.
You have tried so many many devices that you must have a very good bearings to what actual works the best..
With most comparisons, people tend to find a default product to comapre against, what is your best product over the long run ?
Can you use this as a comparative product to evaluate others against, given price etc..
As I dont feel an exhalation amount means that much, any decent product should give more than enough smoke, my DSE901 seems to be more that potent enough at most times,
though it can be a little random...
To me what is more important is:
Consistancy of exhalation
Quality of inhalation
Battery life
Atomiser Life
Cost
I think you were doing very well with your first bench marks, I feel the chalk marked board maybe wont be so beneficial...
Anyways your videos are excellent, most others on you tube just seem like sales medium, you seem to be genuine in attempting to evaluate these devices, keep up the good work
