It's actually quite easy to know where legitimately sold product goes since most companies track serial numbers. It also isn't unusual for supply agreement to have restrictions on the ability of a customer to resell product. In a case where a company purchases components and secures the right to resell, those resale clauses usually would have a right of first refusal for the manufacturer to repurchase. Most companies know exactly which product they sold to which customer or distributor, so if the parts end up in devices that ultimately end up coming in for a warranty claim YiHi would quickly figure out where they came from.

It's more likely that any product that gets used in unauthorized devices is either stolen or counterfeit. I used to work for a very large analog semi company negotiating their supply agreements and we often had company's seeking warranty claims on stolen or counterfeit product. We had armed guards accompany shipments from our Fab to the shipping point since the trucks were subject to hijacking attempts. It also happened that we had problems with shifty employees taking product and selling it out the back door.

That's interesting. So it actually wouldn't be that hard for companies like Sigelei to find out who is selling their products to fasttech. Why then hasn't this supply chain been shut down. I do know if you buy from Fasttech, the manufacturer’s serial numbers are usually blacked-out on the warranty cards. So all warranty issues must be handled by FastTech. So either Fasttech just takes the loss or returns it to their supplier for replacement.

is the 350 j the same thing as dna40? it "regulates" temp or is just a setting with out measuring the coil? do you need a certain wire? if this is like dna40 with the solidity of the s class gee whiz.

It regulates the temp just like the DNA40. In order for it to be a temp control device it has to monitor the wire. Because of this, you will need to use nickel wire just like the DNA40. From what I heard, they ARE trying to see if they can achieve something similar with Kanthal but that may or may not happen.

So yes, it basically functions like a DNA40 but has the SXMini body. Although some would even go as far as to say that SX350 is better than the DNA40 chip.

" Although some would even go as far as to say that SX350 is better than the DNA40 chip. "

like me, for instance. 60 watts vs. 40watts...upgradeable firmware vs. too bad, you need to buy a new board or device, and very little customizing vs. 3 modes, 5 memory settings, and auto scroll-not to mention extremely accurate. gee, why would anyone think the yihi board is better than the evolv?......

I received my SXmini last week and have been very happy with it until today.

Today trouble started I think--after firing the screen stays lit and will not turn off unless I actually turn off the device. Is there a setting that may have been changed or is this a sign of problems?

I was actually getting ready to order #2 today, but when this started I decide to hold off--I don't want another one if there is going to be problems. I have always been a "Provari girl'--absolutely no problems with any of my devices--and I don't want to deal with problems! I ordered the SXmini as I did not feel the Provari 3 went far enough with updating to what is current today, however I would rather have a problem free 20 watt device, than a 60 watt that is not problem free.

I am really disappointed as when I received this device, I felt it was well built, looked great, and would last a long time. :(

we don't need to start up but just what happened to me. 3 dna40 mods. 3 out of 3 dead. one in an hour. sx mini working after over 1,000ml. I wore out two new vtc5 in the sx mini and it is still going. it's like the freakin' Toyota of digital mods. again, go figure it is from china. every mod I have broke even mechs. the sx mini is the final contender.

I guess I will skip the m-class for now because I use a atlantis exclusively. just what I prefer. on the other hand I just knew they would have the last word on dna40. now you have the (imo) better chip does the same thing.

a while ago someone said I would be eating rice and noodles for praising china. fine. that's pretty much my diet anyways. we only look at the downside of china. they do a lot of things right. including rice and noodles!

I've never heard of this problem. I think it has a 30 second time before it turns off. Also if your moving it substantially the light won't turn off.

there are always a dud to be had. even with provari. my provari's,Darwin and even variant are collecting dust now. it should be a no brainer to get a good one. yihi makes the dealer replace it afaik. it does not have to go to china.

one thing I wonder though. when most Chinese mods stop dealer puts them in the trash and hands another. not worth fixing. provari,hana etc. do get repaired. I wonder if the sx mini gets repaired instead of tossed being that it is not cheap. of course they have bigger volume so maybe they still toss it. I hate trashing things. I keep most broken electronics in my basement. never know when the opportunity to fix something comes along.

Contact YiHi and get a new one through warranty. What generally happens is they will give you a dealer stateside to send it back to, and the dealer will ship you a replacement.

Thanks--no I am not moving it around. Fire it and then set it down on the table--screen stays lit. I waited over 30 minutes earlier to see if it would go off on it's own. I had to power down before it would go off.

I will contact the vendor tomorrow and see what the process is for replacing or repairing.

I'm getting my first TC mod (SX Mini M Class) soon and have never worked with nickel wire that I can remember for sure. So I'm not sure what I should be buying to stay within it's .08Ω, 60W range. I have kanthal in 28 AWG, 30 AWG, and 32 AWG, also getting some 26 AWG, but I don't have any nickel...what do you guys use on your TC devices, or what would you recommend?

28ga Ni200 is the "default", though a lot of folks have had good luck with 29, 30 or 32 gauge, the latter two lending themselves well to twisting (which offsets some of the wire softness issues, as well as the regular "benefits" of twisted wire).

Few people go heavier than 28ga because of the sheer amount of wraps needed to get resistance above 0.1 ohms, which is the functional limit for DNA40 devices.

With the SX350J, I wouldn't try to build down to .08 in any case, it's got at least 20 more watts to play with compared to the DNA40, so personally I'd be building higher resistance (which is about the same as the target range for a DNA40) and take advantage of that extra wattage.

Long time no "see"... Good to see you here, but sorry you're having issues. IIRC, I remember reading of a similar issue on one of the international forums awhile back. YiHi is supposed to be working on a solution in their next firmware update. In the meantime, try hitting the fire button, or the top adjustment button one time after you see the display light stuck on, to see if it shuts off. I would still pursue an RMA and get a replacement though.

You know that I'm a ProVape fan also.. ;) I placed my purchase of the P3 on hold since purchasing the SXmini. I'm that impressed with the device. :) I was going to buy a 2nd myself before I heard of the upcoming SXminiJ M Class next month. There have been some cosmetic changes, along with the addition of temp-protection. I'm sure that the firmware will be more refined also. The SXmini is the only Chinese regulated device I've bothered with in over 4 years with the exception of the Sigelei Zmax a couple of years ago.

I 'm still around the ProVape forum, and have read of an issue or two with the P3 also.. I know it's a great device, but anything with electronics involved can be subject to issues at times. I wouldn't give up on the SXmini just yet.. ;)
