You brought up soem great points in you post Darcy- will be waiting for his answers to them- I would think that the 22 hours included some sleep time- perhaps 8 hours, so that would actually bring the 'smoking time' down to 14 hours, and down further if he actually set it aside for a couple of hours durign hte day? These questions need to be addressed. I did a couple of reviews of the SmartFixx penstyle where I counted each puff (not too har to keep track of as I would smoke ten puffs each 'smoking urge', and stop or go to 20 puffs, and record the tally) and got to over 400 puffs on one cartridge and 350+ on another- both prefilled carts- but the taste and nicotine were kaput past 200- but htey did go well over 300 with good vapor) This would be a better way to judge the longevity of each loong cartridge I think- it's a bit of a pain to keep track of the numbers, but doen in groups of 10 or 20, it's not too difficult to keep a mental tally going.
If one loong cart can easily go 400 puffs, that would be = to 40 ciggs, or two packs of ciggs- then we could calculate cost vs. time by how many regular packs we smoke per day- I'm a 1 pack a day smoker, so if one loong cart lasts 2 packs worth, that woudl be two days worth of smokin for me- better way to judge how long it lasts than by hours because we would know exactly how many puffs each carts gives.
trust me the loong cart can easily go 400 puffs,now about the nicotine towards the end it dies out ,and like i said the flavour sucked from the start to finish,if the flavour was anything rather than plastic it would be the best e smoke ever i hope they can make more flavours in the future.
the smoke is crazy ,much more than a real smoke.
it cost me 250 australian dollars with 50 cartridges a bit high but what the fuuckkk,if it lasts its better than buying cheap ****t.
