I haven't tried this, but heard great things about it.... Not so much rebuildable as replaceable core. I left links back a few posts ago, its the ce5+ for $6 and separate cores are like $1.76 I've heard great things, and honestly, its half the costs of the others, with excellent cost on replacements. You can peek at Discount vapers forum if you want to hear what people are saying about them. The vivi nova sounds great, but I know 3 people who haven't been able to get it to work, period, so that may not be one unless you're a serious tinkerer. DV has about 3 new low cost rebuildable options, so I'd peek in the 'tanks' and 'cartomizers' sections...new ego tank, and one other along with the ce5. I will tell you... Eric at DV tells you exactly how things work, warts and all, so the descriptions will warn you of any possible issues with any of his stuff. Also, I've not heard good or bad about these, but I know
Parkes Vaping has an 'acorn' tank, very inexpensive, and I believe that's rebuildable. Just remember if you're using any 'ego' device you need a 510 to ego adapter on a regular mini, 510 to 510 shorty adapter on any chrome or stainless mini.
And yiddleboge6, I talked to Eric about that, and he says the manufacturer (vision, I believe) says they are upgraded. I think he mentions in the description what they're made of. I can tell you that even the CE4s were pretty durable. I break EVERYTHING and I only managed to break one of those... and that CE5 is 2 incarnations further along than that.
And I promise you guys...as soon as I have a few dollars I'll try one of those and report. But i can say I liked the CE4 a lot more than I would... only issue was the stubby wicks. So the ce4+ with longer wicks was an advance, and now the ce5+ is very exciting. He also has a ce6... but I have NO idea what that guy is... looks more like a phoenix than a ce5.
And Carolina... I'm with you on the zen tanks! So want one! So will never have one! rofl Oh, and I do have 'edit button' on this thread... might just be something wonky with your browser, or ecf. I run into issues when my 'like' button disappears constantly, and everyone else still has theirs. lol And as for a 'true' rebuildable tank that lasts ages... nope, I don't know of any offhand other than the really pricey ones. All I know in reasonable range are the sort of 'disposable rebuildables'. I will say that the inexpensive manufacturers are just starting to experiment with those, though, so I have high hopes for the next few mos seeing some exciting inexpensive options in rebuildable tanks. I want vision to make one in the same 'pliable' plastic they use for their 'grande' with the colors... that would be fabulous, and I find that plastic doesn't get the hairline pressure fractures something like a CE4 is prone to.
