Burnt Taste in MF Blank Cartomizers Fixed?

[MichelleDen]

If they taste/smell like burnt urine..hmm
Maybe Leaford knows if there's any disgruntled workers where they make these8-o
weirder things have happened....

 

[caged]

Bloog cartos do not use solder. Earlier in this thread I disassembled a couple cartos and the atomizer is only mechanically connected.

Any chance some of the connections are loose and allowing for a small amount of electrical arcing?

Hi everyone, sorry for my absence, but the last week before the holiday always gets nuts. Long days at the factory, and holiday parties and celebrations at night. (It's a hard burden, but refusing would offend them so what can I do? ) And of course in the midst of this, my tablet pc crashed and when it came back up it had lost its network drivers, so no internet. I should have probably kept up on this thread at least using my iPhone, but I hate trying to forum post on it, either in Safari or TapaTalk. Sorry.

Anyway, Most of the week was working on the cartomizer issue. There simply wasn't any time for them to make manufacturing changes before the holiday, but I did implement a pass/fail test as promised, and now all blank cartos will have a guaranteed 2.4-2.6ohm range.

I doubt it accounts for all of the problems, but I did notice in observing the testing that there were about twice as many rejected fo being too low resistance, than for being too high. The bell curve seems to be a bit more lopsided than I expected. Which leaves open the possibility that the burnt liquid problems are all caused by the low ones. Again, I doubt it, but it is possible.

I shared posts from this thread and the feedback thread with the engineers. It took some doing to get your concerns through to them. Despite the earlier conversarion with the chief engineer at the beginning if the month, they hadn't implemented the ohm testing I instructed them to while I was gone, so when I got back from my visa run I had to make them retest all of them.

Anyway, when I discussed it with them I had to break through the usual engineer's attitude, which is always tough even with my friend. They kept insisting the customers couldn't possibly tell the difference since it's not enough difference to substantially impact vapor production or puff count. That's why I showed them translated posts, proving that not only can you tell the difference, you guys MEASURE IT. I'm not sure I got the message about the burnt liquid through to them, though. Hopefully by the time CNY holiday is over I will have some burnt examples to show, I think that's what it will take. Jay, you sent yours back, right? Right?

 

[leaford]

Oh, one more thing I found out, their design-phase testing indicates that vapor production drops off above 2.7ohms, which is why they set their parameters so most cartos are in that range (which I just this moment realized explains the lop-sided bell curve).

What does that mean for us? Just that I need the feedback on the 2.4-2.6ohm range before I can say for sure whether we will raise the range. I still think we will, and if we do, I will check the vapor productiin carefully. I do NOT want to sacrifice vapor.

Hi everyone, sorry for my absence, ...how, I think that's what it will take. Jay, you sent yours back, right? Right?

- Welcome back Dan (got Mike yet?)
- Crap! I did not send those "burnt ones" back because we were still testing and we (I thought) came to the conclusion that they were not excessively blackened and the filler was not black at all.
- I still have some of the blanks and can "recreate" the culprit liquid-batch blank result if you like. If so, can I mail them to you there in Shenzhen or do I need to go through Jersey?

- By the way I filled one last night with a new liquid and it never fired up at all (dud), so I am glad you are testing them.

I found the two coils photographed earlier in this thread, PM me with instructions Leaford.

Jay, what I really need are intact cartos with the burnt taste so I can stick them in the engineers' mouths and say THIS is the problem. Then, let them take it apart and see what they think is causing it. Not disregarding what we've worked out here, but I think we need the experts' analysis as well, rather than going on just our speculation.

Got one filled blank that tastes bad labeled with it's liquid and "#1" SCRATCHED INTO THE LABEL.
Want it or should I wait til I get another?

Sounds perfect. Just send it back to bloog at the return address with a note identifying it.

And anyone else, too. Please! We will credit your shipping, but the more bad examples we have the better.

On the way in mail today, I had another one at home so I mailed 2 filled blanks with bad taste...

Wonderful, thanks!

I'm glad to read that you're working on making the blanks work better. And I'm assuming that the blanks you have available now may still have the problems? Why is it only the blanks that seem to have these problems, and not the filled ones?

Thanks!

We'rre still working on figuring out why it's only the blanks, Newme. But the current batch of blanks have a narrower resistance range, 2.4 - 2.6ohms, eliminating one uncontrolled variable. We'll get there. And it's worth noting that as many people have reported the problem, many others have said they had no problem, which is why I am still suspecting either the resistance, the liquid, or the combination of the two.

Thank you for replying Leaford! And on a good note, I love your products!

• Almost all my liquids are VG and none are vaping well - all my VG tastes bad in the (prev. sold out old lot) low-Ohms blank cartos.
• But I dug up some PG today, real thin stuff from Tasy Vapors, and tried it. Vapes well with no bad or burnt taste.
• Anyone get the latest blanks yet?

 

[jayvap33]

• Just tried another new one (old style, fresh unopened blank carto I mean) and it's spot on. PG IS OKAY IN BLANKS is my take.

60pg/40vg and 50/50 are working out great for me, but that's refilling a prefilled not a blank.

 

[leaford]

Ypou know what I really want? High speed micro-resolution footage of what's happening on the heating coil itself. That's where the rubber meets the road, and we don't know enough about precisely what happens there. Even if it didn't help us solve this specific problem (although I think it would help morethan speculating without it) it would just pkain be cool to watch! Right?

 

[trichman]

I can say for sure that the prefilled are improved from the first batches. Now, I can hit them hard on my passthrough which is my preferred method of vaping and they rock! I am on my second box and no problems with any of them. Good Job tightening up the resistance! Thank You!
