S-Coil MTL - 1.0Ohm

Customer Reviews for the S-Coil MTL - 1.0Ohm (JAC Vapour) 5 Pack

• Generally reliable coils - by Bruce, 11 May 2021
  4
  These coils I've found generally very reliable (with a Series B DNA 75), certainly compared with the previous Kanger ones from my old tilt vape.
  I budget that 1 coil will last 2 weeks, but on average I find they last up to 4. I tend to find I'm replacing them not because they get burned or leak like the old ones, but because they simply wear out & produce less vapour, which is fair enough.
  Quality consistency is OK generally, although in my latest pack of 5, 3 lasted about 4 weeks, one lasted 10, and one was a dud, having a really tight draw, with wet crackling (but no burning), which I replaced after a day. Dunno what happened there, but in general a 5-pack I expected to last 20 weeks lasted 25, which I'm satisfied with.
• Using far more liquid than previously - by Chiri, 29 March 2021

  I’ve enjoyed a happy consistency with these for several years. However I’ve found I’m having to use significantly more liquid to prevent burning - to the point of increasing my liquid use some 50% though I don’t believe I’ve increased how much I vape by such a extreme volume.......... JAC Vapour: The only way it can use more juice is if the heat increases, increasing the vapour production. This can be done by lowering the ohm of the coil, so if the coil was reading low at around 0.8ohm, or the voltage has increased in the battery. So if you have fixed voltage device, the battery is regulated to 3.7v, if this failed somehow it could go to 4.2v when fully charged. If you wish to return some of the coils we can check, but its not an issue that has been reported by others. One thing that can happen is as situations change vaping habits change, and it can be unperceived. I am not sure of the your circumstances, but due to covid we have been working from home, and I have definitely started vaping more, just because I can pretty much do it whenever I want, I don't feel like I am vaping more, but I know I am because I can see I am using more juice, plus my wife is telling me. You can also check by trying to count time vaped or amount of drags, and we can compare to a setup in the office to see if the drags/time roughly match. Obviously if doing drags, the length of drag is important. The final thing is juice, if you switched from a PG to a VG base, then VG based eliquid produce more vapour, and hence use more juice, they are also smoother so easier to vape more. Please contact customer service if these info does not help.
• Poor performance lately. - by Gary, 16 February 2021

  Something very wrong with these over the last 3 months. I used to get 7-9 days out if a coil, now they are lasting a maximum of 4 days, mostly 3. Also seem to be hammering liquid, 3 tanks a day rather than 1.5.
  
  Its a shame as they used to be great with the VIM but I'm now looking to move away from Jac Vapour after many happy years. The usage of oul and coils isn't sustainable for me..... JAC Vapour: Thank you for your review. I am sorry of you are experiencing issues, but if I had to guess this sounds like a tank or device issue, if it is effecting every coil, maybe the regulation on the voltage is no longer working on the device. For it to get through more juice the device would have to start producing more power, and that means the coil ohm would need to drop, I have the coils here and can see they are consistent within 1 ohm, so if you are getting consistent issues then is must be the output of the device. The device is semi regulated, so we regulate the battery down from 4.2v when fully charged to 3.7v, maybe somehow this is failing. Please contact customer service and maybe they could help, It could be your device needs replaced. The other thing to try is the 1.2 mesh, this uses slightly less power, and the new tech may help, it would definitely be good to compare. Again customer service will be able to help with this.
  
• Hack to fix coil - by Sarah, 10 January 2021
  3
  Had the same problem as many others, ie coils tasted burnt quickly. I had a closer look at the coil and noticed that an air bubble had developed in the coil and stopped the flow of e liquid. Pricking the bubble and priming again seemed to fix the problem. It only seems to affect the coil when it is new.............JAC: Thanks for the tip, if that fixed it, it could be the cotton is a bit too tight, and pricking it has fixed the issue. The cotton in these coils is hand fitted so this does make it harder to be consistent, add on top of that the virus has meant a lot of new workers that are not as experienced, the more mature a line with experienced workers, the more consistent. From starting a line to peak consistency it normally takes around 6 months, so we are bound to have a few issues carrying over for sometime, and hopefully we won't see the same issues this year, and not have to re-train all over again. If anybody experiences any issues due to these effects, we can replace quickly and free of charge.
• A dud pack? - by Chris, 12 November 2020

  Normally I don't have any issues with these coils other than the odd dud one but I've only just started using the last pack I bought in July and they've been horrendous, some have lasted a couple of days others have needed changing almost immediately. Thank goodness I usually buy a couple of packs at a time!..............JAC: Sorry you have experienced an issue with the coils, if you contact customer service they will replace the pack for you free of charge.
• My 2 cents... - by Gillian, 6 September 2020

  I had to jump in here like Graham and defend these coils, I have never had too much of an issue with these coils and any I have had, jac vapour have always been excellent at resolving the issue. I hope these will not be discontinued due to a few bad reports because I am moving back on to these after finding the mesh coils a bit too strong on my throat. That’s just a personal view. Sure these don’t last as long but I find it’s a much smoother draw from these coils and you get more for a lesser price which justifies it for me..................JAC Vapour Ltd: Thank you for the review, and there are no plans to stop these coils, they are our most popular coil, so this and the 0.5ohm DL coil plus the mesh 0.8 and 1.2 coils will continue.
• Good only when they work - by Morgan, 24 August 2020

  I have been using these coils for some time (over a year) and just recently something has gone very wrong. Some coils last me a couple of weeks, which I expect as I only vape lightly, then others last maybe a day or burn out immediately. I have gone through numerous packs of coils and am close to just buying another brand of vape. I love my S-22, but with 3 days delivery, there have been occasions where I have bought cigarettes to last me since my last 3 coils all burnt out immediately leaving me with no other choice. It is not my settings and I always prime/leave half an hour before use with a new coil. I can only assume this is a problem with these coils, but the cost and inconvenience are persuading me to just cut my losses and buy another vape so as to avoid this issue. It’s beyond frustrating. ...............JAC Vapour: Thank you for the reviw and sorry you are having issues. I have checked with issue reports and currently issues reported are consistent with our normal rates, no coil is 100% and it is possible to get duds, although in general the s-coil is one of the more reliable ones, we do have a new batch in of the MTL 1.0 coil so if you want to contact customer service, you can get any problem coils replaced with the most recent batch, or ask to try the new mesh coil, this could also be a better option. Most users reported a marked improvement over the standard coils.
• Quality eliquids and devices but poor inconsistent coils - by Caroline, 21 July 2020

  I've been using these coils for over 5 years now and had intermittent problems with them. Some packs are fine but then I get duds that taste burnt very quickly and occasionally straight away. Recently I've had this problem with these and the new coils. Sometimes it's the whole pack and other times one or two in the pack. Just to confirm my settings are all ok. 12.5W, temp off and watts mode using the Series B DNA 75W.
  I've had some replacement packs foc but I'm really fed up not knowing if I'm going to get a good batch or duds again.
  I haven't written a review before but this time, after it was suggested I was doing something wrong, I decided to write this.
  I don't change my settings therefore I don't understand why some coils are ok and some are duds . Is it manufacturing?
  I've sent various messages and got replies quickly but now I've read some reviews and I know it's not just me.
  I've been asked to send a video of my settings but I know they are ok. In any case why are some coils absolutely fine and others duds on same settings. I've sent in batch numbers too.
  I like the JAC liquids and the Series B but the coils are not consistent and it's becoming quite costly having to replace after a couple of fills or immediately. I've spent a lot of money with JAC over the years and don't enjoy being fobbed off. Once again they've offered foc coils but I'd prefer to have consistently good coils. I took a pack on holiday last week and used all 5 in a week as they all tasted burnt after a few refills. I've opened a new pack and so far so good. Very hit and miss..................JAC: Thanks for the review and I understand it's frustrating. Coils vary as they are hand wicked, so there is room for human error. So no coil is every 100% good all the time with all liquids, the mesh coils attempt to take the margin for error out of the wicking so they tend be more consistent. We do have a few recent bad reviews and hence we have investigated, but issues reported to customer service are no higher than usual, and when we test random coils they all work as normal. Thats' not to say there isn't an issue, it just means we can't recreate it and seems to be only affecting a small number of users. This makes it very hard to track down the issue, and in turn solve, as we have yet to manage to get it to happen on any units ourselves, and I use these coils everyday. Assuming you are priming from the top and have not changed eliquid or anything, I am not entirely sure what is happening, but potentially if you get replacements and you get a failure right off the bat, maybe we could get that pack back, and test with an identical setup and liquid. So please contact customer service if this happens with your replacement pack.
  
  
• No Issues here - by Keith, 26 June 2020

  all fine with my coils. Having said that I tried the mesh 1.2 and I far prefer them. When they get better value I will move to the mesh.........JAC: The mesh are now a 4 pack, so you are around the same value from them as the MTL now, we originally sold them as a 3 pack in the test order, so maybe you have not noticed that update. Thanks.
• It's the coils again - by Geoffrey , 22 June 2020

  hi sirs
  The write up for your coils states" in time your coil will need to be replaced"
  I wasn't aware that meant every day.
  Out of my last 45 coils from you s coil 1.0 Ohm
  I have had
  5 coils on which the metal contact had snapped .( and NO it wasn't the way I removed them from the foil.
  2 coils which would not screw into the body of my S22,
  2 which would not work at all
  And of the rest the use time is between 8 hours ( not continuous vaping ) and 2 days ( never over 2 days)
  To say I'm disgruntled would be an understatement
  I didn't complain at first thinking it may be a bad lot. And I know you guys would be tied up in the pandemic situation.
  But enough is enough I feel I've got to make my voice heard.
  At the price of these things and the higher prices for your new coils, I may be better off going back to the cigs.
  Hope this is published as I really am a bit miffed
  Pete Moore........................jAC Vapour: I am sorry you are having issues, the best thing to do it contact customer service. The metal contact snapping off a coil I have never heard of, it also sounds like from your wording that the same thing is happening with the mesh and normal mtl coils. This could mean there is an issue with the device. We record all the cases of coil issues reported in customer service, and I checked the other day, and rates are normal, we always get a few reports, no product is a 100% perfect. So we are not seeing any increased rates of reports from customers at the moment or in the past, despite more than normal mentions in reviews. if you have not already done so, please contact customer service and we will try and get to the bottom of your issue. If you have any failed coils that you have retained, then potentially we can get engineering to look at them and see what the issue is.
