Was thinking I should've kept my mouth shut... but it's looking better now.

Out of the blue, the first one puked about a ml across my mod and hand. Uh oh. :eek:

Turns out, after 6-8 refills... the spit-guard cap had unscrewed enough to open the wicking.
Fixed it and checked the second... same thing, but I caught it early.

Not something we've had to keep an eye on before.

I have got one today to build a coil for the very first time.

It's very easy to build it and there is no leakage. However i used the wire which comes with the kit. I had no idea about the wire specification and the user guide do not contain any information about this.

It's working on 0.48 ohm and jumps to 0.46ohm when i vape on 30W. Is this normal or am i doing something wrong?

Just as an update:

5mm overhang was too much I'm now going around 3 mm for tucking into the juice holes and the leaks come usually when the tank is almost empty. Using two o rings is hit and miss - sometimes they creep up the thread and make the base sit bad. When I do it right so they stay where they should it works great.

I finally dropped my tank enough times the chimney broke away from the tank completely. It lasted 8.5 months, not bad.

Just trying to choose whether to get an isub Apex, Vortex or S. Still using a original Coolfire IV, saving up the pennies for a TC as I just blew a load rebuilding my car's engine.

3.5mm is a big mandrel but fits nicely in the atomiser and easy if you just need to dry burn and re-wick. I've tried smaller coils but to get close to 2.0 ohms makes them too wide (too many turns) for me. Tootle-puffing for life :)

The only recent iSub I was considering was the "S".
But I've been reading that it's prone to leaking and possibly other problems. An issue of complexity or perhaps user error with its' many parts.

Now however... there's the upcoming "V", which appears to be essentially a basic top-fill "G".
I like that and I'll be keeping it in mind.

The RBAs are still working perfectly BTW.

I haven't had any issues out of my isub-s. I've been using it for at least 3 months without one leak. It has also set several days without use, full of juice or on the lower end as well. I really like the bars protecting the glass too.

The current issue I am having is how hard the draw is on the clapton coils. Now I used the standard .50 horizontal coils for over a year and didn't have this problem. I'm going to try another clapton tonight and see if the first was a dud. I've been vaping on the first coil for over a week at 33-35w. Maybe that coil type is just not for me.

I love the Aspire clapton coils though but I like the Innokin coils better on the price point.

This is so sad... I absolutely LOVE my iSub Gs, and finally learned how to rebuild the stock coils, after having kept them going with dry-burning and rewicking for over 8 months, however, the rubber insulator tore on a couple of them, causing shorts. So I ordered 6 of the RBAs, thinking those wouldn't have that issue. I agree, building the first one or two was excruciating, but I can do it now with no problem. However, ALL of them leak to some degree.

I found a discussion (doing a web search) on reddit and every person that had them said they leaked. Then I come here to see if any of you were having problems with leaking, and see yes, LOTS of people have issues with leaking.

This is just depressing. I have had nothing but great luck with anything Innokin makes (I've never had a Coolfire IV, though ;)), and this RBA seems to be so SHODDY. The cap is a MF to get on in the first place, then it backs off while it's in the tank, and I'm not sure if that's what's causing the leaking or if it's just leaking down the center, but what a PITA these are. I don't have a lot of money to begin with (living on SS retirement) and I feel like I just threw away fifty bucks, which hurts. I'm thinking maybe that fifty bucks would have been better spent on a different kind of tank. I hate this, because these iSubs are my daily drivers and now I don't even want to use them.

Does anyone know if it's possible to get a bag full of those rubber insulators that are used on the stock coilheads? If I had a bunch of those, I'd just keep rebuilding the stock ones (and they're a LOT easier to do!). I haven't been able to find anyplace that sells those, however, and I can't afford to keep buying stock coils. And anyway, what if they're not available after a certain time? I'd really like to keep using my tanks, if I can figure out this whole coil problem.

I get a bit of a gush from most all of my RTAs (and RBA heads)... usually about the third draw of the day.
Takes a couple to get them warm I guess.

So I always have either a paper towel or even better a TP square to catch it and they're ususally fine after that. And that's important because... the iSub RBA caps unscrew slightly every time I refill and a bit of paper is the only way to get a grip on it. Slippery stuff that VG. :p

I also agree threading that cap is a mother. :mad:

I never did get around to opening up any of my iSub, or K Sub Tank, heads. Someday I may, I've got several sitting around... but for now, I'm much happier with the RBA heads for my iSubs.
I do wish the coil leg holes were slightly larger though.

Let me know if you want to sell me two or three of them.

I did a test this afternoon. I took the RBA out and cleaned EVERYTHING up. I actually have three tanks (HAD three) with those in them. The ones that I wasn't vaping on were fine. I took the tanks back off after a bit and checked, and there was no leakage. The one I was currently using was puking a drop of juice onto the 510 pin on every draw. I took the tank off after one draw, and yup, there was juice on it. I cleaned it out, cleaned the bottom of the RDA, took another draw, took the tank off... more juice. When I checked the other two, they were still clean and dry UNTIL I took a draw off of them. Then I took the tanks off (after just one draw), and they each had a drop of juice on the 510 pin (you know, the thing inside the mod that the tank "pin" part touches, I might be using the wrong term). One drop is no big deal, but after vaping half a tank or so, all those drops add up and overflow underneath the tank and down the side of the mod. Not to mention the coil head itself being DRENCHED in juice when I pull it out to re-tighten the cap. o_O

I thought this was such a great idea, but now I'm thinking, not so much. I took those out and put the rebuilt stock ones back in (the ones I didn't tear the insulator on - LOL!), and they're just as dry as a bone, as they always have been.

I would give just about anything to be able to find a supply of those insulators... Or to figure out SOME way to keep these RBAs from leaking!

@Innokin_Ash is there some kind of fix for this?

Have you tried using a bit more cotton. Wicking these right is a delicate task. I have an iSub, iSub g and iSub Apex 5. All of them perform flawlessly with the RBA head. I did had leaking issues in the beginning but after a few rewicks got it to work just right every time. I use them often and have refilled each more than 10 times and they are still leak free.

Thanks, Louie, I use rayon, and I can try using more than normal. On the regular stock coils, too much would give me dry hits because it didn't wick fast enough, and I finally found the *right* amount to use for a perfect vape every time. But maybe I'll sit down today and try jamming extra in one of the RBAs and see if that helps. Keep your fingers crossed! :)

OK, so far so good! I put more wicking in one of these RBAs and I've been using it for about 30 minutes and so far, it's still clean and leak-free. I keep flinching, waiting for a dry hit, but I haven't had one of those either, yet, so it looks like it was just me being dumb again. :oops:

Thank you very much, @louiesquared :D

You're welcome. The coil diameter in the RBA is quite large so it requires a good amount of cotton. Or rayon in your case. I hope it continues to be successful for you.

The coils I'm making for the RBA are the same diameter as the stock ones (3.5mm), so that shouldn't make any difference, but who knows? The extra rayon didn't hurt. Anyway, I had no leaks at all for a while yesterday, so I finally quit checking it every few minutes, and then BAM, I had juice all over again. All in the 510 connection, running down the side of the mod, into the firing button, everywhere. (I'd let it sit for a while during dinner preps.) Apparently, there wasn't enough vacuum in the tank when it got below about half-full. It was fine while the tank was full or almost full, but leaked like a sieve when the juice level got below a certain point. I don't know for sure that's the problem, but I assume it is.

Anyway, now I'm back to square one. I'm EXTREMELY disappointed in these. I have one thing left to try, and that's to use cotton instead of rayon. I like rayon way better than cotton, but since cotton tends to swell when it's wet (and rayon doesn't), maybe stuffing it with cotton will help. If not, these things are toast.
