ok. so my 2 choices are disposal e-cigs and refills:
re disposable, if he only smokes a few puffs at a time, I guess he can put the cig back into its case and until the next day or something. will it go stale or evaporate after a certain number of days. or can it still be usable after a week or so (sometimes he does not smoke for over a week)
it seems cheaper than the disposables. for Jet Black Triton Tank Kit
but after that, I guess I will have to get him refills, which costs about $6 each. how long does a refill last? and are there other parts I have to buy besides the above costs?
