thanks for posting Trog- hmmm- I am honestly gettign quite a few more Real cigg's worth from my cartridges for the SmartFixx [provided we're counting 10 full drags = one real cigarette- which as I've said, I have tested by countign my drags off a real Cigg]- maybe that will change as my pen gets a little older [it's only 4 days old right now] and the atomizer gets a little weaker. The vapor probably starts dropping off around I would say 10-12 real ciggs worth, but it's still ample vapor for quite a few more real ciggs worth. I'm goign to say that after the first test with the brand new pen where I got 370 full draws and good vapor, it's probably dropped to around 200 maybe [I'm just guessing, as I haven't counted full draws since my first test- but I feel safe in saying it's around at least 200 now], but again, this could drop off as the pen gets older too- we'll see. Since Monday, I only have 5 used Cartridges, and two of them were quite dry and only got around 10-12 real cigg's worth from them, and I've been smoking fairly steady, although yesterday for abotu 4 hours I experimented with homemade smokin juice mixtures and refilling- but then went back to the prefilled Cart [mainly cuz I 'needed' the nicotine lol].
I'll test another prefilled Cart tomorrow and see how many full drags I get from it just to be sure- I'll stop the experiment when I feel I'm having to work the pen too hard to get a good amount of vapor- just like my first experiment- 370 draws was still producing some ok vapor, not great, but ok- enough to satisfy the feelign of taking a draw off real cigg- though perhaps it was morel ike takign one off an ultralight cigarette at that point- by 350 [having to take double draws in one breath to produce enough smoke to satisfy], at around the 350 mark, it was like having to work an light cigarette to get an ok amount of smoke I would say- But then again, I'm sure the Pen came with a 'juice primed atomizer' and this I'm sure skewed the experiment.
