i'm definitely in the same sort of "i want an ecig/pv that at least MOSTLY looks and feels like an analogue" camp. my heaviest cigarette/cigar smoking has always been when i am on the go (ESPECIALLY walking or driving places) and being a fairly small person with literally child-sized hands makes some of the larger batteries/mods/what have you (stuff i have tried from friends) not only impractical, but make me look somewhat goofy (and feel like everyone is staring! so NOT what i am going for!)! there are some DECENT disposables out there (and when i say "decent" i basically mean they will do in an absolute pinch) - among the 10+ kinds i tried before i went the rechargeable route, i agree that the njoy kings aren't too bad - if you don't mind blowing nearly $10 a pop for something that can last for a few hours of moderately heavy vaping to 15 minutes (i live about an hr outside nyc and had purchased 2 njoy kings for the trip, the second of which - and the last i bought - was blown by the time i was out of the lincoln tunnel!!). AT ANY RATE!! the first kit i bought was the blu starter kit which, in my opinion, really does a fantastic job in "recreating" the feeling of smoking analogues. however, my "praise" of the blu basically ends there - my batteries last me 15-20 mins MAX and at least 45 to charge, i have not had pleasant experiences with their customer service, and i have found the refill cartos not only to be insanely expensive as a legit cigarette replacement, but extremely dry and bland tasting compared with the cartos initially included in the kit (i have purchased the refills from a variety of vendors as well, so i am "assuming" distributor handling is not necessarily to blame). i do still keep my blus charged, mainly for VERY short drives and in case my other cartos/clearos run dry or i forgot to bring something while i am out (note: i did NOT mention battery drainage as a problem there!!). i have tried the v2 but wasn't thrilled - the vapour production seemed poor to me, but to each his own. what i am now using (and THRILLED with) are the smokeless image 78mm auto volts (i'm ordering a manual and deciding on an x2 just for comps) - i have had mine for nearly a month now, and with due care (i do keep everything very clean and i make sure to keep one charging while i'm using the other), i can honestly say that even vaping pretty heavily for several hours in a row, i have not experienced even one instance in which either battery has started to lose power on me (of course i probably just jinxed myself saying that!!) - my juice tends to run low way before my batteries do ... which is definitely a "problem" with which i can live. the size is great - bigger than the blu, no doubt, but it still fits very comfortably in my teeny tiny hands - the rubberised finish on some of the colours (not on my chrome/silver one but i still love it!!), like the njoy kings, really does make it "feel" more like an analogue. i ordered some of the si "xl" blank cartos and i must admit, i do prefer the "regularly" sized ones, both due to the overall resulting size of the volt units as well as they seem not to dry out as quickly on me, for whatever reason. so that's that! my apologies for being so terribly long-winded, but honestly i was and continue to be amazed by these si volts - they have helped me out in quitting the cigs/cigars more than i can say (i am a newbie, but it has been 2 days since my last analogue and i have been/had smoked for the 10 previous years - aaaahh starting in high school!!) - with good juice/liquid i have found myself actually preferring / reaching for my volts and getting somewhat disgusted by the thought of lighting an analogue when i used to NEED one (like first thing in the morning). i wish yinz luck and hope your brother-in-law can find the "perfect" ecigs!! with all the products and setups out there, the options seem pretty limitless and incredible!
