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

  • Great coils when they work. - by Stephen G, 10 January 2019
    I love the S22 tank, the Turbo coils as well as these but it got to the stage I needed a more reliable tank/coil. I have given these coils another chance, today another one burnt out for no reason after a couple of days use and thats on 15w 60/40 juice. I now have another Aspire Tank which is a lot more reliable but if only gave the same favour for MTL. Its a shame, I have been using this product for a couple of years but given the coils are not widely available in vape stores its time I changed brand.................JAC Vapour Ltd: it sounds like you know what you are doing, but the only 2 things I can suggest, are make sure you are priming from the top of the coil, so 3 drops in the top of the coil and then 2 drops on each wick hole, this is needed with 60/40. Also if you are using nic-salts (not sure if you are not) but this is the only thing I have seen affect these coils, if you are the 1.5ohm coil is much better with any nic salt based juice. If you contact Customer service they can explain in more detail, and replace or change any faulty ones.
  • Good when they're good, annoying when they're full of duds - by Simon, 12 December 2018
    I love these coils when they work, they seem to last forever for me (and I vape all day). I only change them when it's not as good as it could be, I never get dry hits or anything. I use Tobacco Silver from Jac by the way. But sadly I always cringe at a coil change, putting it off as long as I can. Sometimes even vaping my S22 TF right down to the last - just maybe so I get a forced dry hit?

    The reason for my reluctance is that they're so unreliable. Out of my current pack of 5, 3 have been duds. One was, what I would call as a Cigar fan; PLUGGED. And the others just leak, leak through the holes, spit back at you regardless of tank clearing tricks. And yeh, I do prime them every time.

    I wish they were more reliable because I love the S22 TF, but the coils need serious work, if this unreliability can be identified at manufactuer level...................JAC Vapour Ltd: It sounds like your coils are flooding, if this is the case you just flick the device ( in the instructions) and it should clear. While we do get a few users that have issues, it's very rare, and I use these coils everyday myself, as do many people in the business, and I have never had a coil leak in the VIM or the S22, a new coil does always gargle after priming from the top, but a quick flick and it's then good. There may be another issue, possibly with the actual device, but if you are doing as advised, I would suggest you contact CS and we look at changing the tank, to see if that helps. I have seen one unit that leaked consistently and it turned out to be that the chimney had been over machined and was not connecting fully with the coil, so it could be something like that.
  • Great Coils - by Matthew, 5 December 2018
    Great little coils that last forever, well they last a damn long time! I love these coils and not had a dud one yet! Both me and my OH use them in the S22 and the Vim and they are superb.
  • Not as good as others. - by Gav, 27 November 2018
    First of all, Jac make some nice products. I really like the design of their tanks and the mods. The coils let them down, and that's true for the DL, MTL and the Turbo-S versions. For the purposes of this review I will focus on the S-Coils MTL 1.0 Ohm. I use 50/50 liquid and vape these between 12 and 15 watts. Anything higher pushes the coils beyond its capabilities. I've been vaping for 5 years now. I vape sweet and/or fruit flavours.

    The flavour is just not as good as some competitors, namely Aspire Nautilus and Innokin T20 S. It starts off well albeit without the depth of flavour of the coils I just mentioned. Flavour very quickly deteriorates to almost nothing. Numerous coils burn out too soon and often they seem to get 'blocked' so that drawing on the ecig becomes too much bother to be worth the effort. On those occasions I have disassembled the tank to check for blockages in the chimney, coils and base but there have been none. The intake holes on the coils seem to be too small to keep up with regular vaping and they're placed too high on the coil so that you need to refill sooner than you should, despite the fact that the coil sits deep in the tank in an attempt to off-set this. It's a design flaw which suggests they designed the tank around the coil - but the coil is the problem.

    Clearly a lot of thought has gone into the products and the quality of build and materials is up there with the best. I prefer the tanks to the Nautilus and T20 but cannot regularly vape JacVapour products because of the hassle caused by the coils, which is a real shame. I've never had more than 5 days out of these, and that's WITH the flavour vanishing after 1 or 2.................JAC Vapour Ltd: I am not sure what is happening here, I use a 65% VG base at 18 watts and never get a coil burn out. I know you are an experienced vaper, but this is not always obvious, have you primed form the top and bottom of coil, i.e. 2 drops on each wick hole, and then 3 drops into the top of the coil (basically down the centre of the coil. Our wicks are more tightly packed than others and require priming from both ends to get the flow going. I do know some nicsalt bases reduce life, bu in my experience, they reduce life on all coils. If you are wicking from both ends, then I suggest you contact customer service and we get the exact liquid you use, and we can try and mimic the issue on a device here, juts mention that you have had this suggested by the engineer that answered your review, thanks for the feedback.
  • Not all 'duds' are faulty coils - by Iain, 20 November 2018
    I’ve used Jac for several years, now graduated to s22 - happy with these (ok, a bit of spitting and gurgling when new and uses liquid quicker than old geni aero 1.5 ohms). I have gone through a lot of coils in this time and it has been rare to have a dud. I use mtl 1.0 ohm in s22- not needing to go to DL/ turbo/variable watts or volts.
    What I have found is that sometimes the new coil doesn’t fire initially (with all due preparation) - if I take out the newly replaced coil then reinsert it carefully and tighten strongly in place, it then works. Also not to over tighten the tank on to the battery.
    My problem then is changing the coil when there is liquid in the top-fill tank - I have to plug the mouth piece while inverting the tank to refit the coil - loses liquid and is a mess when it does.
    Just a thought that maybe a lot of reported 'duds' may be due to the coil just being a thou out in replacement - even with my 'experience' - it’s my user dexterity more often than not that is at fault! (I use PG > VG for my taste so not sure if some problems may otherwise be due to viscosity of higher VG liquids for some).
    If CS can advise a trick to change a top-fill coil without losing liquid already in tank that would be a bonus............JAC: Thanks for the pointers, the last quarter turn on some coils can be a bit tight, so maybe that is the issue, without that last turn the coil does not connect properly. As you say, also over tightening the tank this forces the spring loaded pin right to the base and it can basically cause a short, the battery safety then kicks in and prevents firing of the tank, all tanks should juts be finger tight. In regards to replacing the coil without a mess, you need to make sure the liquid in the device is not full, so if you turn the tank upside down and the liquid is touching the coil, the tank is too full to replace the coil, you need to vape it down a bit, and then replace the coil. If you can imagine the coil meets the chimney forming the sealed tube for the airflow right through the tank, so splitting this while liquid is past where the coil meets the chimney allows all the juice to run down the chimney and out the mouth tip. Basically you can only replace the coil when the tank is half full, in most other modern devices you actually have to have an empty tank to refill.
  • never had a dud - by Gentgeorge, 15 November 2018
    After being part of the original testing group (I know there have been others), and using these coils all the time, I can safely say these coils never have an issue, and I mean never, not one dud in over 18 months use. I wouldn't normally pipe up about this, but I see a few reviews that people are having issues, and that is not a proper reflection of this product, and I would suspect down to user error, read the instructions, prime properly, and these will never let you down. You won't get a better stock coil than this, and if you don't believe me go and check out a forum like Planet of the vapes, there are whole threads devoted to testing jac coils and devices, no other manufacturer even does that sort thing on the level of involvement jac does. used properly these coils last weeks and I know some guys on the forums have been running the same coil for months.......JAC: Thanks for the review and glad to see you are still using the coils, we appreciate all feedback good and bad, and we can't assume any failures are just user error, every case needs to be looked at. Thanks for the positive comments.
  • very happy - by Jenni, 13 November 2018
    got given a vin by a friend and after trying these and the bigger ones, I have settled on these with raspberry very very tasty. my first pack has lasted me 2 months, so this is the first pack I have actually had to buy myself, so I will report back if there are problems. So far I am loving not smoking though.
  • More duds than I'm willing to take any more - by Kath, 6 November 2018
    When these work they are very good. However there are too many duds I'm sick to death of contacting customer services who I must add are very good and replace them but I'm not doing that this time as I get sick of answering the same questions over and over again. This time I'm putting it out there. I've just had 20 duds in a row, Yes 20! all 'batch number 241' they last a day then die that's another £20 down the drain Jacvapour your products are good apart from your coils which let you down big time................JAC: Hi Kath and I am sorry to hear you are having issues still. It looks like you have been having issues since moving to the s-coils, and that shouldn't happen. I am actaully currently using the batch 241 as well, and my first coil is 4 days old, so I have not noticed anything. I am juts checking, that you are priming the coil, this means, 2 drops on the wick holes and then 2-3 drops down the top of the coil, if you are only leaving to sit then the coil will burnout, as the wicking process is never started properly. The cotton in our coils is a bit tighter than most, this gives longevity once started, but means they absolutely require priming. So I am juts checking that is the case. If you are doing that, then the only other option is to get the kit back and see where the fault lies, as something is obviously not working as intended. I will get customer service to contact and check if the above advice has worked or not, and if not organise to get your unit back, it will be free and we'll organise it in a manner that suits.
  • Simply too many duds - by Nathan, 5 November 2018
    The first three coils --fully primed -- in my current pack barely lasted 3 days. Something is definitely awry with the QC. At £10 per pack, this is unacceptable. It appears JAC are no better than Innokin et al, but I'm willing to give the 1.5s a shot before ditching the S22......................JAC Vapour Ltd: Thanks for the feedback, please contact customer service with your details of setup and they will get the coils replaced, as the issue is unlikely to be the coil, although it's not impossible. They will be able to help get the coils running as expected.
  • Best stock MTL on the market bar none - by Philman, 31 October 2018
    I have tried all the s coils over a period of about 2 years now. I have gone from MTL to sub-ohm and DL, even temp control, as I attempted to find what suited me. One of the nice things about the Jac products is the flexibility, it's not the best DL or temp c, but it's a solid introduction and enough for me to try and have the novelty wear off, just too much of a faff, as they eat juice, but nice to give a spin every now and again. I also moved to the Turbo coils for quite a while, and whilst they are good, I can ramp up my watts on the DNA and get a pretty similar experience, if you are a fixed wattage user then you might gain quite a bit from them though. The fact is I have always run this coil in one of my tanks, it's a solid MTL, I'd even go as far as to say for a stock coil it's probably one of the best as it can handle any juice you throw at it, that includes notorious coil destroyers uber high VG or Manabush, in fact I have run this coil with pure VG and it copes, same goes for the DL 0.5, to my knowledge that is not possible with any other stock MTL coil. My only niggle would be that the flavour on some juices is a little muted, but the upside is that this coil will last for an age, and never miss a beat. In a pinch I have run a coil for 3 weeks, and it was still acceptable, that's crazy life for a MTL stock coil. I do like to tinker, so I play around with the latest RBAs and RTAs now, but always my goto for out and about is this little trooper, if I had to go away for a week and could only take one setup it would be my DNA 75 and the S22 tank with this coil, any other setup and I'd be nervous about being left high and dry. Top marks to this coil, and jac for a great product.
