My experience with hte mini is that they indeed do spit fire and belch dog pooh. The cartridges only last a few cigarettes, and hte draw is quite hard to get any good vapor- but mind you, I've only tried two minis of hte same model, but from everythign I've gathered, quite a few others experience similar problems with outher brands.
I don't particularly like toting around a
device like hte pen either, but I much prefer the convenience of longer lasting cartridges (I've gone as long as 430 full draws- the equivilent of 43 real cigarettes- but that was really pushing it- generally I get an average of 20-30 real cigg's worth out of one cartridge as compared to about 3-5 real cigg's worth from the minis I have. I have popped in a new cart this mornign at 11:00 and the Cartridge is still goign strong after near constant puffing. I don't go as long on the cartrridges anymore because I don't want to push things too far, so I'll top the cartridge off with my homemade smokin
juice later this afternoon aroudn 3:00 or 4:00 p.m and do so for hte remainder of hte day- usually topping off about 5-10 times as needed as the refilling for some reason doesn't last as long as the prefilled carts do- not sure why.
The other negative experience I have with hte two minis is that again, they draw hard, and they heat up quick and they get super hot unless I baby the thing, which won't produce good vapor if I do that. The other hting is that it shuts off far too quick for my taste- aroudn six seconds of drawing on it which isn't nearly enough time for me, and hte unit blinks for 19 blinks, which takes too long for it to be ready again for another drag.
The battery life is ok- provided the battery is newish, but hte ones I have really start going downhill quite fast after a week+ of use
If you're concerned abotu hte looks, perhaps order two models, the super mini and either the mini or hte penstyle- the penstyle can do the heavy work at home, and the mini can be taken out in public (Although I carry both and just use the penstyle whenever possible as it gives much better vapor with less effort-)
and to be honest, my mini atomizers didn't hold up nearly as well as my penstyle ones- but again, I've only used one brand and can't comment on other brand's performance-
