If it sounds too good to be true, sometimes it is. I heard about these and tried some about a month ago - what a disappointment. Obviously everyone has different expectations, criteria, likes and dislikes, so just take my opinion into acount with others. I 1st asked the owner of Litecig what he thought and he relied that he didn't care for them (he uses Boge). He sells them for 8.95 per 5-pack, so I don't know where anyone is getting $3 each for them. One would think with such LR and two coils they would be great. Sorry, I got mediocre performance. Good taste, but poor vapor (compared to what I used to) and a tighter draw. I used them w/ a 3.7 v mod (which peaks at 4.2 v right off the charger) and an ego. The LR also runs down the batt very quickly - takes a lot of (batt) juice. To me, another big disappointment. I've not used one yet w/ higher voltage - maybe then? Best thing I've found yet is Boge, but, as always, will keep trying.
