I dont believe that the 510 is cheaper at all as you have to buy lots more parts. I saw where someone put a list of what to buy for a 510 the other day in new members section and it added up to $100. You can buy a complete 2 battery kr8 kit for $50.
This is utterly ridiculous. Nobody needs to spend 100$ to try a 510. Why is it that in so many threads KR8 fans turn up and make such utterly ridiculous statements? Do you need lies to sell your favourite toy? Truth doesn't cut it?
That list you talk about most likely included PT and PCC and quite some backup parts. With those, a KR8 is also not cheaper. A starter kit for a 510 is about 35$ in the US, and that contains all you need; although you probably should buy some liquid, too, when you start out. Just as you would make sure you have enough cartomizers.
And just in case that was coming up: Yes, atties for 510s are more expensive than cartomizers. With cartomizers, though, you are lucky if you can refill them a dozen times. A 510 atty lasts longer than that. Considerably longer. Which does not make cartos less expensive than 510s.
When scanning the forums, the majority of issues are with 510's but there are only a few problems here and there with kr8's. (is this because more people own 510's?)
It may have something to do with how some people attack everybody who dares having a problem with their favourite toy.
Speaking about juice, well I love flavor! The kr8 gives tons of quality flavor and the cartomizers have never gunked up on me but i have heard people say that the 510 doesnt produce as much flavor. I see people post all the time that you have to be careful with juice in the 510's because the color/thickness can gunk it up. I have never had an issue in a cartomizer even with my 100% vg juice.
Yes, well, for that first dozen times you refill, which is the such a high number of refills for a carto, a 510 does not have problems, either. And I really don't think that if you try to refill a carto with coloured or gunky juice, the cartos swallow that without any complaint.
So for me, I did not chose a 510 simply because I didnt want to deal with juice in my mouth, having to store it a certain way in my pocket, attys that taste burnt, have gunk in them or primer, fluval, ptb, constant dripping or refilling. Just give me my kr8 that delivers consistent vapor and flavor for hours at a time by just screwing on a cartomizer.

Funny. I've had juice in my mouth with my KR8 just as much or little as with my 510 (actually condensed water with a hint of juice - doesn't taste good, though, either). I don't have to store my 510s in a particular way, either, I have not yet had gunk in my atties, it takes me less than a minute to make a card mod that works fine for a week, refilling my 510 is easier than refilling a KR8, and I don't get burned plastic to inhale.
