What the Hell is it with VaporDNA's Project Subohm RDAs?

[NateHevens]

I have bought four RDAs from vapordna, all Project Subohm. First was the CLT V3 Infinite.

It read at a 0.09ohms on my reader unbuilt. So I emailed them, and they sent a replacement. In the mean time, I managed to fix the first one. The second one also read at a 0.09ohms on my reader, but I managed to fix that one, too. (BTW, by "fixed", I mean "got to read at a 1 on my ohm reader unbuilt). Bolstered by my experience being easily able to fix the CLT, I ordered a Swirlfish. Same issue, but this time, I couldn't fix it.

Got a replacement, same issue, only, again, couldn't fix it.

Figured "third times the charm", though, and got a Mutation V3. It read at a 1 on my ohm reader. Made me so frickin' happy, I got a third Swirlfish... which failed again and I couldn't fix it.

However, the new Mutation V4 came out, and since the V3 came perfect I went ahead and bought it...

Well, it's reading at a 0.08ohms unbuilt, and I can't fix it. I don't even want to email them for a replacement, because I'm fully expecting it to be the same, and I'm really sick of this same thing over and over again. VaporDNA's customer service is wonderful and the response time is almost lightning fast, but a) this is product after product, b) you can't tell me they aren't getting sick of hearing from me, and c) if I'm the only one they keep hearing about this from, there's no way it isn't starting to look suspicious.

But there is simply no way I'm the only one experiencing this. It's not my ohm reader, which has fresh batteries and reads all un-shorted, built RDAs accurately. And yet I still got a smok Omnitester which is on its way, just in case.

So what in the hell is going on, here? I may get a regular, non-Project Subohm Mutation V4 from somewhere else and just get my money back on this one or something, but I'm really at the end of my patience with this. It's ridiculous.

If you get Project Subohm RDAs, please check them on your ohm readers. Somebody... please somebody... say I'm not alone in experiencing this.

Please.

I never tested one unbuilt.

Ya, I test all of mine unbuilt when I get them just to make sure there is no machining crud in them. But never have I had one not show an open circuit. Ha, ha. Thats not to say they did'nt have crud in them, it just was'nt enought to cause a short.

sounds like an intermittent problem with the ohm meter and the center pin.... try another meter.

 

[roxynoodle]

I've never tested an atty unbuilt either. Guess I never realized I should.

I usually always test the centerpin with a meter just to make sure it's not some plated crap gonna add .2 ohms or something,

but since the kraken from fasttech last year coming dead shorted out of the box I admit im paranoid now and always check so I dont drop more springs (rhodium plated silver springs arent cheap) lol

 

[Stringplucker]

I agree with Bunnkiller...check it with a different meter and see if it's the meter or the RDAs. I have one Eleaf meter that always reads 0.05 with an empty RDA. It's sitting in the box, in my shop, marked, so it never gets used for anything...until I decide to tinker with it.

As some other posters have stated, I would check with a different meter for sure, if the batteries are low in my meter it will read very very low resistances when there is nothing to read at all, even turning it on with nothing attached can make it act wonky with low battery level.

While I do never test a brand new RDA I do tear them completely down and clean them thoroughly so I figure if it has a hard short by the point I'm building on it then it's entirely my fault anyway for doing a shoddy inspection during re-assembly.

So I got the Smok Omnitester in the mail and that's not reading the Mutation X V4 at all. But that's okay... I bought a new, non-Project SubOhm one from another site (with a discount coupon), so it'll be interesting to see how that reads.

FYI, the Omnitester has absolutely no problems with the RDAs my other ohm reader reads fine, but doesn't at all read the ones my ohm reader shows a short in... so... yeah...
