Is it shortening the long-term lifespan do you think? Or is that something that doesn't concern you - ie. you're just going to toss it at the end of the day anyway?
It might shorten the life of the cart but then again im not really concerned with that. I believe i can get 3 or 4 days use out of it before I throw it away. But then again even if its just for 1 day im still ok with that. I was spending $15/20 per day smoking cigarettes and the occasional $20 monte cristo. At $2 for a cart and maybe $1 for juice im still making out like a bandit.
And when my juice box comes in maybe this will all be a part of the past.But with the current technology available i believe that the cartomizers offer the best available "convenient" vaping experience.
