lol Kit- when I first read your comment, I thought it said "Cool method mate I think you're cracked up" Which, if you had, I would have had to agree 100% lol
In the mornings (11:00 a.m- Yup, I get up at hte cracl of dawn lol) I put a prefilled cartridge in because I take the pen with me to the resturaunt every morning, and smoke it while waiting for my breakfast, and the prefilled Carts don't have quite the smell that my homemade smokin juice does, and I'll smoke the prefilled cart until it starts getting dry- usually around 3-4:00 p.m, then I'll start refilling it. The vapor cloud I get with the refilling is quite a bit more dense than the prefilled cart produces, and it's also a heavier hit/feel when inhaling too which I forgot to mention. The prefilled carts produce a lighter vapor and draw.
I'll test it later tonight, but I think I'm getting about 1-2 hours smokin when I refill- Not sure why, but the refilling doesn't last as long as the prefilled carts for some reason, but 1-2 hours is plenty for most road-trips if indeed that's what I'm getting- As I mentioend, I'll test it tonight to see just howl ong I get on a refill- this is all steady smoking too I smoke constantly with hte pen- much more than I do if I am smoking regular Ciggs- with regular ciggs, I go 1-2 hours between cigarettes, but with hte pen- I'm smoking steady- I guess it's to get enough nicotine to keep my levels steady- but hte point is that when I say I tyhink I'm getting 1-2 hours on a refilled Cart, that includes the fact that it's a steady 1-2 hours of smoking- if I were to smoke it like I do my regular ciggs, I'd probably get quite a bit longer time out of a refilled cart.
