Well, I suppose I'm about done with the KR808 XL test. This is the one that was tested just like it came out of the box. It has not leaked and the performance has been satisfactory for several refills. Other than a nasty taste to begin with, it has worked as advertised. Therefore, I cannot gripe about how it works now or in the future. It's too bad that a higher percentage of them cannot accomplish this.
With that said, this cartridge began having a wicking problem after several refills. I first noticed it when it only took about 1 ml to fill it. Before long it was less than that, until it only had a good taste for a few minutes after it was topped off. The vapor was always good, even when it had a burned or dry taste.
The advertisements for the E2 make no claim about dry burning, so I did not perform one to remove the black crud. Naturally, I thought this would fix it. It did not. Well, maybe a little bit, but hardly enough to notice.
Now, BanjoMan has already dry burned with the filler ring in place, so there is not much of a reason for me to add to it. It seems that only a few of us are doing a burn with the ring installed, so I'll just say a couple things for the benefit of those who do.
I used an empty syringe to get any remaining juice from the reservoir. It's best to do it with the needle instead of the plastic tube. First pull the plunger all the way out. Then insert the needle in a hole and point it straight up with the cartridge suspended. Any remaining juice inside will drain to the filler ring. Tilt it a bit to favor the empty filler hole and pump the syringe. This compresses the air inside and the pressure forces the juice out of the empty hole. Pump it several times if you think it needs it. Air goes through the needle quick and easy, so it doesn't take but a few seconds.
The wick will still be wet after this, but I did not completely burn all of it out to clean the coil. I just smoked it out enough to get a red glow and then burned it enough times to get a reasonably clean coil.
After that I washed it out a bit. Not the entire assembly. Just the inside of the cup and coil, which also includes the air passage. To do this, I went to the kitchen sink and got a mouth full of water. Then blew it through the threaded end and out into the sink. I did this a few times, then followed it with air to get rid of the excess. Maybe this got some ash and crud out, I don't know. I did this with water because I did not want to waste my Smirmoff or Crown Royal. This process did not get any water in the juice reservoir.
Then I did a burn to dry the remaining water. There was no smoke, but boiling water bubbled out of the hole when the coil glowed. After a few pulses, I quit when it began to smoke. This was a sign that the juice from the wick was getting to it. I then filled it with juice and vaped. It didn't wick worth a poot. Everything I wrote above was a waste of my time.
This ends the test with the filler ring installed. Now I can take it out and get my yummy back.
The filler ring had some black crud underneath, especially where it fits on the rim of the cup. Also two distinct black marks that mate with the slots in the cup. After a good scrubbing, these marks are brown and look like the photos that BanjoMan posted. However, there is no damage to the silicone and I cannot feel a depression or anything else irregular with them.
So, now for the good vape without the ring. It's not all that good at first, but surely it will get better. It don't. I use a miniature awl and punch the wick. Nope. I lift it up, poke some more and shred it. Nope. I don't know what's the matter with this thing. Maybe it is supposed to be disposible.

I can't seem to find the ceramic kr808 carts in stock anywhere! They sure look nice COV is going to have them but they are showing out of stock.
ya.. me either.
I thought I'd pickup 5 just to do the crazy test thing. Didn't someone say they were recalled?
No recall that i know of, they will continue to sell the revision 3 and improve revision 3 as well by not using any primer and also adjust the leaking issue from what ive been told.
In a week or two revision 4 will be released after its tested, it will have the fixes i just mentioned and most likely a new ceramic cup design to stop any seepage from the slit or wick.

I appreciate seeing your videos, bad. Now for a question. Do you have a quick and easy way to reinstall the filler ring? I doubt if I will be using them all that often, but I haven't mastered them little suckers yet.
I actually do and will upload in a few, just got a new camera so let me install the software. Its not 100% fool proof since you always want the cup flush in the middle as much as possible but i find it much easier with the soft inner plug then the old one.
until the video is posted I basicly use the end of the needle syrying cover, its slightly bigger then the hole and seems to push the inner plug in the middle causing the sides to over lap the lips of the cup. then i tilt the e2 and press the edges down like using a mortar
Thanks for the update 'br'. I'm finding the same w/ my two 808 XL's; the wicking is pretty good on one and so/so on the other and has a lot of the dry taste. I didn't disturb the filler ring on mine and filled w/ a syringe. My friends wife's, the leaking carto I wrote about yesterday, proved to be leaking again today. He said his leaked a little but that was probably due to some splatter in the air tube.
Nice vid's 'bad', I'll look for the filler ring video soon.
the filler ring has to small of a airhole, the center hole needs to be alot bigger, once its enlarged it tastes and works as if there isnt a plug there at all.
ill add that to the video as well..
To avoid leaking on leaky e2's fill your e2 under a light and try to keep the juice under the cup, this removes much of the headache.

Actually, I remember you saying that you did, and that you would make a video of it. I was just jogging your memory, heheh.
Normally I fill one to the bottom of the cup to prevent some of the leaking. I can't see the cup with the filler ring in place, so I have a tendency to overfill it.
Here is a video showing that the leak doesnt seem to be coming from the bottom, i was also testing the camera.lol
You can all do this test without cutting it, just fill it with juice but under the cup as to avoid leaking from under the cup. then using like a end of a pencil or something, push down on the ceramic cup while holding tightly to the e2, it will expose the center pic at the connector, if the leak is coming form there it should leak as you pop it out, out of all of them i get no leaking until its actually popped out. under all other tests it doesnt leak until its broken .

Don't know if anyone else has the parts and wants to try this but I've been testing it and it seems to work. I took a brand new 510XL and pulled all the rings out. Then I took the plastic filler ring from one of my older E2's and used a dremel with a small cutting bit to enlarge the inside of the hole just enough to fit over the ceramic cup. It doesn't sit as close to the wick as the silicone filler ring but you'll know you're there when you can install the other ring and mouthpiece like normal. I filled it with juice to the top of the cup and put everything back in.
The first few times I set it on its' side I got a little juice in the airtube. Since then I've let it sit for several minutes at a time and it's working perfectly. It measures 2.6ohms and I'm using it on a 3.7v box mod and it's wicking fine. I've even held it upside-down and I'm still getting no juice in the airtube. Best of all it pops out easy for drip-filling. This is only the first one I've done and it needs more testing, but it looks promising.

That old plastic filler ring was nice to get in and out, look forward to hearing the update 'banjo'. Another nice vid 'bad'. My friends that leaked did have some come out the base as well as in the mouthpiece. I guess it may have back washed out the base possibly?
Not sure turbo, all the ones i tested I cant get to leak from the base, meaning a actual leak form the bottom area inside the e2 where the center post is, i have no way of testing the cup leaks since once its cut in half there is no way of replacing the top half after sealing the cup to stem area and cloaing off the slits, so the only thing i can test is to see if any leaking occurs at the bottom form the inside of the e2 and i cant get to leak unless i popp off the whole post like i did in the video.
the video is finally clear, it seems it takes like 10 minutes for it to be truly uploaded i guess
i was hoping to find it leaking at the bottom form the inside, then that would explain the juice in the airflow but then it would be more clogged then it is so im sticking to my original theory that the leak is coming from the cup and stem area and the slits.

It's probably just juice that got in the airtube that "looks" like it's coming out of the base. Once juice is in the tube it's going to leak out of the battery end.
i cut open a few that had no leaking at all, and what i noticed was looking at where the cup sits on the stem, while its super tight and looks sealed on the leaky ones it looks like there is a gap so even though its tightly on the stem somehow juice is seeping up in any space there is, some dont have this space for juice to go upwards into and thats why those dont leak.
On the ones that dont leak, if i remove the inner plug on some i get leaking coming form the slit area and on others they arent leaking from the slits area, the ones that do leak in the slits area seem to have lots of space where the wick sits in the slots(slits) and has room for juice to escape into.

So do you think that if they make the slots in the cup just wide enough and just deep enough for the wick to sit in without compressing it we might have a winner?
Thanks guys, that would make sense, even if the leak isn't happening at the base. The liquid will follow the path of least resistance and end up at the base sometimes.
I know one thing, when the wicking is 'on' like the one I'm using, the flavor is amazing.
