Seriously, using Cartos is no big deal. You fill up 2 a day and your good to go. Takes me 5 min every night. (well with me its 3 or 4 because I have turned into a vape fiend..lol)
I thought exactly like you and wanted to stick with something that looks like a cig... and my Halo G6 has done me OK.. but wish I would have started with an eGO RIVA or something that I can slip in my pocket and last me all day at work. I go through 2 batts right now at work.... and by what I hear the taste with the KR808s..cig size is just no where NEAR as good as you get with something slightly bigger.
AND...the price for a decent Cig style PV is not much less (or a bit MORE) than a good deal on a eGO.
From the halo, if you are looking for flavor, skip the ego and go right to a Riva/KGO, there's a lot more to it than battery size. I don't want to say much more on a noob thread with the headline "I'm so confused" and ask that we not get into a discussion about watts here. Trust me, I wish I had when I was ready to step up from my kr8s. I stepped up into a battery that lasts longer but puts out less power than a kr8. Riva/Kgo are the same power with a world of choices to place on top.
What you two are doing, even if you don't realize it, is making the case for VV PV's. But this thread is a nOOBs thread who is trying to get started. Let's just keep it simple.
