    So I've had this tank (Vaporeeso Estoc Mega) for about a month now and gone through 8 coils (0.5ohm ceramic euc coils rated 25-35 watts). All of these coils have been perfect, perfect, perfect. Amazing flavour and vapor. 2 days ago I was using it on my kanger subbox while waiting for my xcube ultra to come in the mail. The coil I was using was going perfectly but it felt a bit harsh and I felt it needed to be changed. So I took out my 9th from a pack of 10 and it felt so different. By different I mean it didn't sound the same as the previous ones (made a nice crackle but never spits liquid up) and the taste of my juice wasn't as strong with a slight burning sort of taste. These coils do have some cotton in them and I'm sure it wasn't he taste of burnt cotton. Once I received my xcube I tried it again and had the same effect. Tried temp control mode and it was a bit better but still shitty compared to what I had the first 8 coils. Tried turning the wattage up to 50 and the juice taste was there more but so was the weird burnt taste. Tried my old coil, the 8th and last good coil and surprisingly it still worked fine. Still harsh but was working as expected unlike the 9th coil. So I tried a 10th coil hoping the 9th was just a bad coil but I had the same unpleasant experience. Went off and bought a new pack of 10 and I've tried 5 of them to have the same thing happen! With my first 8 coils I didn't even prime them I just put them in, filled the liquid and it was good to go every time. With the last 7 coils I've tried out I have experimented with priming and without to no benefit. I've tried cleaning the tank out and boiling it and putting a new coil in again with the same results. I'm stumped now . Tried going back to Clapton and titanium in my griffin and sun tank and I couldn't stand it after my good times with ceramic! When it was working out for me it was just too good and I really want a solution. At the moment I've bought a second estoc in hopes of a faulty tank but will be waiting a week or 2 to get it in the mail. I couldn't even find a relating topic on the web so I'm hoping for some positive feedback here, fingers crossed!

    Couple things could have happened
    First the most probable is bad coils (it happens)
    second thought, was that some how the power/Wattage go bumped/changed on the mod and you burnt out your coil.
    I doubt the tank is to blame. Good luck and Welcome to VU:wave:

    Unless a ceramic coil design is different im under the impression you ALWAYS PRIME a replaceable coil

    With the kanger subbox it's a VW only so no temp control or mode change issues possible, I have tried priming 30 minutes but no good results. I'm struggling to believe I had 7 bad coils in a row (exact same effect). Debating whether I should try every single last one of my coils to see if I find a good one?

    What was your wattage set at and which coils do you have ? (wattage rated) I have this tank and using it right now.
    And like Mike said, did you prime the coils first?

    I had it set at 33 mostly while I had the good coils with ceramic EUC coils rated 25-35 watts. I've tried all sorts of wattages with the bad ones trying to find the problem ranging from 25-50 without luck :( it's an amazing tank and I love it so much but need to get past this issue now

    I think it's notable I had a similar bad taste with the Clapton EUC coils rated 35-45 watts

    When I start a new coil, I start it low and work up the wattage to break them in slow, I use the same coils(25-30) right now I am vaping them at 18 watts on a Pico, works really good for my type of vaping. You didn't say yet if you primed them

    I primed some and didn't the others to see if anything changed but it didn't. With the first 8 coils I used I didn't give them time to prime at all they were fine to use within 10 seconds

    he didn't prime 7 of them then experimented with priming on the other others but that didn't fix the issue.

    my guess is youre getting bad coils or not breaking them in properly...That's one thing I hate about premade screw in coils but its what you have to put up with until you move up to a tank you can build your own coils on...Not sure how to help as it doesn't appear youre using too much power for the coils in general but I still suggest priming non the less.

    I used to be a builder too, until I tried a friends estoc and I fell for the new level of flavour and vapour instantly, you should give it a go it's worth it! You can get the tank $15 and coils $10 a pack of 10 at the right places ;)

    drop liquid down into the coil and make sure all the cotton is primed...install the coil and fill the tank up then let it sit for about 10 minutes...Start off on maybe 20 watts of power to start with then gradually turn it up..Pay attention to the actual ohms of the coil..not all of them are going to be .50 ohm..Some can be lower and some higher..adjust accordingly.

    LOL, few actually exist anymore, the company that sold them haven't made any in quite a while, this one and a white one were gifted to me by a friend a while ago.

    I had issues with mine too. I won an Estoc from Heaven'sGifts and they were awesome, I got it in 4 days...no lie! However, every coil that came with it was dry hit every 3-4 hit. I did prime them properly. Checked seals, reseated seals, replaced seals, still all the same. No matter what I tried kept getting dry hits. So there it still sits collecting dust after very very little use. I thought about ordering a new pack of coils, but I just assumed they are crappy coils since I haven't heard much on the Estoc. Maybe I'll give it another go if it was that good when it worked. I thought since it came with 1 ceramic and 1 cotton coil and they were both dry hitting that something was off with the tank though.

    I found along with priming the hell out of them as you said, you have to ramp them up slowly as well, best thing that worked for me , was to ramp wattage 5 watts at a time letting it set for a few minutes in between.

    This makes no sense to me whatsoever though. I used this tank first on a vaporesso tarot pro and it was so perfect, then on my old snowwolf 1.5 and then on a kanger subbox and for a short period xcube ultra. All so good. I bought 3 more tanks and waiting for them in mail should get them this week. The two tanks that I have tried previously and I'm talking about all estoc Megas were flawless from the get go, no priming time required even. Complete mystery to me and my current tank is still doing shit, sometimes dry hits sometimes just freaking weird funky tastes and not in a good way.
    Will post how I go with the new ones.
    Again guys, when hey we're working, they were heavenly!

    Are the coils and tank verified genuine? My only thought is that maybe your coils are a knock off.

    Me and my girlfriend are having exactly the same problem. A lot of bad coils and sadly only a few good ones. You can prime them all you want, but it does not seem to solve the problem. You can instantly feel that it is not sucking up juice as it should. The moment you put the primed or unprimed bad coil in you will feel a different drag when inhaling through the driptip. We found one solution but it is temporary and oxidates the liquid. There is a transparrent ring in the chimney were you put the coil in. You can remove this ring with a needle. See picture for an indication. However, don't lose the ring because you may need it later. Hopefully someone will come up with a real solution, because when these coils work, they really are one of a kind.

    I ran out of ceramics because they were all shit and I've been using some Clapton coils, they do the same thing but when you unscrew the top cap and let air in it'll increase pressure inside and let the juice soak cotton. When the top is closed it just doesn't soak the cotton with these coils not sure about the ceramics

    Okay so we found the solution. The coil is not the problem, although some seem to work and others don't, but this solution even turns bad coils into usable ones. Also, scrap the last solution by putting the O ring back in the chimney. I went on searching on the internet for other problems, and came across the dreadful airlock problem. This means that when you put the top on the tank and start inhaling a couple times, it will create a vacuum in the tank. This prevents the juice from flowing through the coils, and results in a weird/burnt taste. Apparently, some tanks in the industry coop with this airlock problem. To solve this, you must ensure that the tank can suck more air to replace the liquid that is being sucked out through the coil. Someone, came up with the idea to replace the O ring from the top with a tighter one, to create room for air.


    After discovering this problem, we looked at the original box that comes with the tank and it contains a small bag with rubber replacement O rings. One of these rings is a thin transparent O ring (see picture 1).


    Now unscrew your top just as you would when filling it with liquid. Second, look for the transparent O ring displayed in picture 2 (see red arrow). On the side, you will find two little holes that are made to pull out this O ring (see green arrow in pic 2). You need to pull this thick O ring out with something sharp (we used something pointy like a knife but be cautious). See picture 3 how the O ring must come out. Now you are finally there.


    Lastly, you can put in the thinner O ring. At first it will look like it is too big, however, just put it in with your nails or the back side of a knife (be cautious not to damage the O ring). When the ring is in place it is hard to see it but it is there and it will do the job (picture 4 result). START MAKING BIG @SS CLOUDS AND ENJOY THE FLAVOUR!


    SIDE NOTE: The weird thing is, Vaporesso already provides you with this smaller O ring. So, they must know that the problem is there, why would they otherwise even bother providing this O ring. Very strange!!!!! Anyway, enjoy the flavour and let me know how it works out!

    Thanks for the fix. I still don't think I'm willing to buy more coils to try if it works. I'm sure the flavor on my Crown and Starre Pure are just as good. It's a shame they did that...their tank might have become more popular if they fixed it before selling :(

    Hi everybody. I am currently using the New Vaporesso Nebula with a Veco One Plus tank which uses the new EUC coils. I've been getting that same weird burnt taste. I've looked into and I've found the problem. I've also gone through tonnes of coils. It was perfectly fine at the beginning and it is a one off vapour and taste these new euc coils.
    The problem lies with the liquid, we all know some liquids are sweeter than others. Even though can be all 70:30 VG which I used I found different level of sweetness. Recently been using the Fantasi range and these liquids have an awful lot of sweetener. What this is doing is that it's clogging up the EUC coils and therefore not allowing it to absorb the liquid like it should. I've changed liquid 2 days ago and been vaping at 35watts and I'm a chain vaper so I do really do get the coils working.

    The solution is change your liquid and use one with less sweetener otherwise you just got to keep priming them constantly which is quite annoying. Please let me know if this helps.

    There are other threads on other forums that do mention sweetener killing the coils.

    I bought the Vaporesso Estoc tank, loved it on my Kanger Kbox200. The .4 cotton coil it comes with worked well and actually hasn't burnt out yet. I noticed when I used the Aspire Cleito on the Kanger Kbox it almost always taste burnt. So I bought the replacement EUC cotton .5 coils for the Estoc, I went through 6 coils that all burnt right off the bat. I primed them, even over killed it by dropping the coil in a bottle of liquid for 2 hours, still burnt. I came to the conclusion that it has to be the Kangertech Kbox. It doesn't always want to read a new coil, and it always makes whatever tank I use taste burnt or strange. Like it's not reading the coils right. You have to trick the box into reading the coil right by unscrewing the tank while it's on, and then letting the ohm read 9.99, then screw back in and it reads the right resistance when you touch the firing button. At that point it should ask if it's a new coil but it doesn't always do that. I'm coming to the conclusion that it doesn't read the coil right and burns it right off the bat. Today I bought a Vaporesso Nebula Mod and so far so good. No burnt taste on a new hardly primed .5 cotton coil. So it looks like you have the same setup, get a new mod. That Kangertech box is garbage imo, it's clunky and I've heard they have blown up on people. I'm tossing mine, I bought it with a Smok tvf4 tank a year ago and never liked it so much that I never used that tank more than 10 times but thats another story. Point being if you keep burning a new coil, it's the mod!

    I just made this account in order to shout out a big thank you sir!

    I had been getting dry/burnt/weird taste from my estoc tank, and this seems to have fixed it!

    I just experienced this after a week of heavenly vaping on these coils on the Veco Plus tank. threw out two coils after priming and sitting for an hour each.. just nasty burnt taste and my ohm's were jumping around like crazy. .3 ohm went down to .15 at one point.. So changed another coil and for the veco it was it seemed an air lock issue. After i replaced third coil, reprimed and let sit for 30 min this time i unscrewed the top for no reason and bubbles galore came to the top. This time screwed the top back on not so tight and dry hit it a few times then vaped on low wattage and brought it up slowly and now back to heavenly vapes again.. Annoying as hell but i have had issues with joytech coils and smok coils. Its time to get these coils built properly the mods are good coil technology is hopefully next.

    I have had the same exact issue. I LOVE those coils but I have had a pack of ten with only a couple good ones. I tried purchasing the ESTOC MEGA tank (I use VECO which is better IMHO) thinking that would help but it did not. The ESTOC Mega floods every single time and the flavor is not as good because it's a cooler vape on that tank. But I have to say the only real full proof honest fix to this that will end all your troubles and headaches for all of eternity would be to purchase the Herakles Nano Pro/Herakles Pro and use use the 1.8 OHM Ceramic coils. You want flavor and a coil/tank that works with no hassle every single time? That is your solution... Just trust me on this.

    So my experience so far, i just got the Veco tank with the euc coils. I put the .5 ohm ceramic one right off the bat, primed it and all was good and extra tasty till the first tank. I was running in TC mode in my Innokin Kroma mod at 200C/390F As soon as the liquid went low i suddenly realise the coil was burnt. Wattage was really low and not firing properly, i unscrewed the tank and rescrewed it a couple of times and everytime the ohm reading was way off showing .2 or 1.2 ohms.. I inspect the coil and i see there is burnt rubber on the coil and on the base of the tank where it sits.. The weird taste is not burnt cotton it is burnt rubber so it stays there even if you change your coil because there is leftover burnt rubber on the base of the tank..This needs to be cleaned (the gap is really thin in there if you put toilet paper you can see black burnt rubber on it). I am on my second coil now just have a bit of leftover rubber tatse because as much as i tried to swipe it, the gap is really small so maybe i must find a better way to clean it. Has anyone found a solution or an explanation as to why this is happening? Obviously priming the coil has nothing to do with it..Bad coil design?Bad rubber o-ring?bad connection?
