For how long does the rba done coil hold up before needs rewicking? Hope you understand my bad english hehe

I guess it depends. On some juices I can go quite a while without rebuilding. I built this coil last week and it's still holding up fine. I rewick every couple of days, depending on how gross the cotton looks. I generally check it once a day. I run some pretty sticky liquid, so it has a tendency to carmelize pretty quickly.

i emailed kanger in china directly about the rba insulator, i stated i had the mini but did not give sertial #, they said i have the updated insulator, my insulator is the clear one, so idk what gives after seeing pics of the broken clear insulator.
i sent them another email stating mine doesnt look like the new updated insulator

Info is confusing I would grant you. I personally haven't had any problems with insulators on any of the units I've tested or sampled. Bad break.

If you have the clear insulators on your RBA, DO NOT USE IT. Either contact kanger and request the new brown peek insulators, or order them from their site. THE NEW ONES WILL MELT. Mine did on my second tank of e-liquid, and I was not using a tank craking e-liquid.

So I received my Subtank Mini on Jan 31, 2015 from myvaporstore and had been using it soley with the RBA head and the premade coil that came inside the RBA. My battery is an Istick 30watt, and I vape primarily at 25-30 watts. Unfortunately I hadn't seen any of these threads at the time about the clear insulators also being bad, and had only saw Phil Busardo's video about the original white insulators and how the clear insulators fixed the problem. My Subtank came with a clear insulator (which at the time I thought were the fixed ones), and I am sure you can tell where this is going....

The insulators melted.

My first tankfull of e-liquid on the Mini seemed fine and I was very happy, but upon refilling, I started to notice a very strange and disgusting taste. I thought at first perhaps it was my e-liquid, so I cleaned my tank thoroughly with distilled water, allowed it to dry completely, and refilled with a new e-liquid. The nasty taste persisted, and it was then that I decided to disassemble the RBA and saw that the clear insulator had melted in half and was coming apart, while the other half was fused to the metal base and into the airflow portion of the RBA.

I immediately cleaned the tank again with distilled water, let dry completely, switched to the OCC .5 ohm head and put new e-liquid in, but I could still strongly taste and smell the remnants of the burned insulator within the tank itself, as could my girlfriend and everyone who tried the tank afterwards. I thought maybe it was just my taste buds since I has cleaned out the tank and put in a new coil, so I brought the tank to my local shop and had a few friends try it out. These people were not present when the insulator melted and had no idea of the original issue until after they tasted it, but were still commenting that my vapor tasted and smelled of burnt chemicals despite the wick being fully saturated and primed correctly as I have always done.

No matter what I do, the tank now tastes terrible with whatever e-liquid or coil I put in it!

This is upsetting, because before this happened, the tank was performing perfectly and tasted amazing. I was completely satisfied with my purchase.

Ive contacted Kanger and myvaporstore but have yet to hear back from any of them. I'm hoping they make things right because I love Kanger's products and reccomend them to all my friends.

I'm having to resort to using my Aspire Atlantis (which I haven't used since I got my subtank mini and my girlfriend's subtank nano) while I wait for this issue to be resolved. Thankfully I rewicked the stock Atlantis coil with some japanese cotton so it doesnt mute the flavor as much as the silica wick did, but its still not as vibrant as the subtank's flavor was.

On a side note, my girlfriend's subtank nano has been performing perfectly and tastes great. I also wanted to say, other than the insulator being bad and messing up my tank, the tank performed great before this issue arose. Its by far my favorite out of the atlantis and the delta ii. I had no wicking issues whatsoever with the RBA and I was using 80/20 VG juice and chain vaping

Also, for anyone who doesnt know (sorry, havent read the entire thread)

In regards to the insulators, from what I hear there are 3 insulator types out there. The original white ones which are known to be bad, the clear ones which were mistakenly labeled as peek insulators and were supposed to fix things but ended up being bad, and now the brown/tan actual peek ones which from what I hear has solved the issue for others, but it might be too soon to tell since they are just now getting them out to people.

From what others have posted here and in other forums, if you have one of the older types of insulators (white or clear), you can contact Kanger and they will send you replacements for free. Unfortunately I was not aware there was a problem with the clear edition of the insulators when I received mine and went ahead and used it :( Im hoping to hear back from Kanger soon!

wow, looks like its more broken than melted, i also have the clears waiting on kanger u.s. as kanger china said mine were good

They arent. The clear ones are problem materials and Kanger is scrambling to replace them all with the brown updated insulators. If you have the clear ones, USE AT YOUR OWN RISK. I wish I would have found this out before I used mine :(

Its literally melted to the base, and into the hole where the airflow comes into the RBA. The other piece that looks broken was dangling when I disassembled my RBA to see what was up with the awful chemical taste and fell off on its own.

I did not build the RBA myself, it came with a factory coil already installed inside the RBA which was the one I used. I didnt have any time to try any of my own builds because the insulator melted after the first tank of e-liquid. The factory coil was reading at .6 ohm on my Istick 30watt and worked fine until the nasty taste started (from the insulator melting)

You wicked it though, right?
