I am really liking the ideal of being able to change out the cotton on the notch coil heads, have to try me some of that!
@CrayCrayRay needs to send me one in the mail to test...

I really hate that guy as a reviewer...
Tungsten has a TCR 0.00450 which is higher than Ti and lower than Ni200. The resistance of my coil only changed 0.08 ohms, if it was Tungsten it would have changed 1 full ohm. Tungsten is really nasty dangerous stuff as well, I'd never use any coils made from it.
I think it is just some janky Chinese Kanthal alloy, I wouldn't put it past Joyetech.
I've been eying this tank for a while, been wanting to try out a ceramic coil tank but not sure how this compares to other ceramic coil tanks. For around$20, it's not a bad price but I don't really need another tank unless it's amazing. Btw, is this tank suited for MTL hits?

Any ideas what the ceramic heads is leeching into my e-juice?
Don't like me clear juice slowly turning yellow.
Seems to be leaking from juiceports(no surprise here!) and it almost looks like rust.
Is it the ceramic or possibly heating wire?
Last time I had this happen was when I was still using gennies with mesh.

I may try a couple more ceramics then. Hopefully the ratio of good and bad ceramic coils aren't in favor of bad coils like 80% bad coils. I've tried 2 so far and both were pretty bad .I'm in love with these ceramic heads. All my other tanks are RTAs, but after all the good reports I figured I'd test drive one of these for my shop, absolutely brilliant. The first ceramic coil in the box was a dud however, constant burnt taste. Re-priming solved it for one or two hits but then it'd dry out again. Using a replacement now, and it's fantastic. The only thing is 60/40-65/35 VG/PG is about the max it'll take, it works with up to 75/25, but the flavour is lacking. Running it at 55W and about half airflow.
The RBA deck is pretty good too, not the best quality but it's a very simple build and easy to wick, and will handle any VG. Great flavour.

Nice work on the dissection! I didn't know the ceramics were being touted as being serviceable. I know mine couldn't be serviced. I thought it was only the notch coils.Okay folks, I finally got around to tearing into a couple of these coils. My first coil only lasted a week and I did have a little leakage with that one so I definitely wanted to get into that one. I was really trying to see if it really is possible to change out the cotton on the ceramic head. I also wanted to see how the ceramic in this coil compares to the sintered ceramic cCell.
What I found was not good, lol. I had a feeling the coil I got with my tank was a dud, and that definitely proved to be true when I pulled it apart. The ceramic crumbled apart! I pulled the wire out by one of the legs and it broke so I had to pull the rest of it out by the other leg and that's when the coil crumbled. This particular coil was not a fully-functioning sintered ceramic head. Bummer.
These pictures are from that coil. After I got done with this one I decided to remove coil #2 from my tank and see what that one looked like. I had been vaping on coil #2 for 2 full weeks and it was still performing nicely, so I suspected it would be in better shape and it definitely was. I did not, however, find any workable way to change out the cotton around the coil. When the ceramic is intact it doesn't come out of the metal housing, so I am not sure why that is being touted as a feature of this coil.
Yeah I was bummed when that first one crumbled like that. There was very little ceramic in that one so I know it was a quality issue. The second one and this new one are sintered properly, though, so hopefully you have better luck with the rest of yours. That's awesome about the notch coil! Does it have a long ramp-up time? That's the one thing that has kept me from trying them.Nice work on the dissection! I didn't know the ceramics were being touted as being serviceable. I know mine couldn't be serviced.

The only two ceramics I opened up the ceramic crumbled like you stated. I thought it may have been because I was rough with them. I guess it wasn't. I still have 9 to play with. Hopefully I get 1 good one.
Still on my first notch head and I've changed out cotton twice when changing flavors. Its like a brand new coil head every time.

I know it. The clapton got dark after 1 tank! The ceramic gets dark quickly, too. I think it's because the juice gets hot. The only ceramic coil I have ever used that didn't get really hot is the cCell. All of the other ones get very warm. I do love the flavor and vapor from the Ultimo ceramic coil, though, and I LOVE that you can vape immediately after installing the coil. These coils may not last as long as Joyetech says they will, but they do provide a great vaping experience when they are working properly.The ramp up is quick, but I have to vape them at 45-75 watts depending on the juice. They just need more power but they stay clean. If I vape a clear juice like naked 100 POG, the cotton stays white. I can't say that about the ceramic or the clapton's.

No problem! I really wanted to see what makes it tick and I am happy to share what I found. I am just as curious to see if they can be deep cleaned so I will report those findings when I get to that as well.Thanks for doing this, CA. Much appreciated. It was being said before these were released that the cotton could be changed with the ceramic heads. I have a feeling that there may have been some confusion and some of the sites that were reporting this were giving the info on the QCS heads for the ceramic heads.
That is a bummer but, I still like them enough that I will keep on using them. Like CA, I love the fact that I am able to vape them right away. No break in time needed. Plus, I am able to vape them at much higher wattage than I am with the cCells. Not to mention that the vapor and flavor produced is just outstanding
The notch coils are pretty awesome as well IMHO
Thanks again, CA!
