HCIGAR VT75 Nano (Redux)

[DPLongo22]

Per recommendations of @Steamer861 and @DaveP , I've given one of my VT75n's a fresh cleaning topped with CRC Di-Electric Grease.

Previous attempts at stopping the resistance-waver (and associated tepid vape) using Noalox and De-oxit have all been very short term. None have carried for more than a week or two.

This recent attempt, using the grease, was done on Saturday, 19-May-18. I will vape it daily, and hope that the problem never resurfaces (because this was always one of my favorite mods).

Let's roll - the clock is ticking.



@Katdarling too, for good measure.

If it makes it a month, the next tube's for you (so to speak).

So that's you tube, or my tube...

Did you happen to see this thread on the Hcigar issues? Did it help if you tightened the cathode screw next to the USB connection? If it's a fix I'll order one.

That's the full sized one, not the nano. They did away with that screw on the li'l guy. Thank you though.

It may be a bit of a wait here, because I want to give it a full month before concluding. I'm pretty sure that all (many) previous attempts petered out before that. For some reason I'm thinking each lasted about two weeks or so.

Kat may recall otherwise but she won't be around until much later today (I think).

I carried it for a while simply because I like the mod so much (especially the charcoal colored one!), but then decided I was being a bit foolish (for my own personal priorities). If this works, I'll be a very happy camper, and will probably owe Steamer a tube of grease (or something).

Post 4 in this thread shows the VT75 Nano disassembled to reveal the screw's internal connection. At least they are referring to both the full size and nano version having the same problem. Not owning one I'm just going by what posters are saying in the threads where they say the Cathode screw fix is a winner.

It looks to me like Hcigar needs to beef up their point to point wiring scheme to ensure reliable contact. Lock washers under the screw heads would be a good start. If the signal path runs through a screw contact chain, they better be able to maintain continuity.

Full-circling back to my original message (other thread) regarding the mod ("There are some issues..."). Yep, and I'm guessing you'd have less issue with it than me, since I've no interest in taking my mods apart to fix what should have been corrected from the start. It's much more likely that it will sit upon a shelf, while I enjoy others. That's just my world, based on my life's priorities.

The "two possible ways to fix this (dayum) mod" post pretty much says it all for me. Too many other options to choose from, and too much real-life stuff to start getting frustrated by a mod.

In all fairness, JAC releasing their B/DNA75 didn't help matters, because the difference in quality was discernible (understatement of the year). The VT75n would never return to its previous status (Primary Out & About), but I'll enjoy it if it doesn't start going bonkers again.

To each our own, and long live the vape.

It's a shame that manufacturing quality control is the obvious weak link in this otherwise elegant mod. If it comes apart easily for repair I would still buy one because I think I can remedy the issues with chain connections by using lock washers and dielectric grease.

Are the electronics, ergonomics, and firmware solid in the HCigar VT75 Nano? If they are, I'll probably jump on it for a sale price.

Very much, yes. Nicely rounded, and feels GREAT in the hand. Just enough styling to make it a little "different", and it's an all-around WIN from a usability perspective.

The battery door takes some getting used to, but it was never the problem for me that others have had with it. I'd avoid the red ones, as that seems to be a common link in that area (my red one included).

The paint is far from the worst I've used, but will scratch if pressed ("Been there, done that"). IF that's an issue, VaporSkinz wraps fit perfectly every time, and the 3M they use doesn't feel bad at all.

If this fix holds up, I'm leaving it naked now, since it won't be going out with me anymore. Plus, it's really nice to look at with no wrap.

I'm pretty confident you'll enjoy using it, and given your inclinations, it might be a pretty excellent fit for you. I hope so, anyway, assuming you go for it.

Stop being a wuss and just disassemble the mod and be done

Nah. I'm a breaker not a fixer.

"Ain't nobody got time for dat!"

Boy, 777777777777, I sure hope you're not talkin' to me! I'm no wuss, but I'm also HIGHLY unskilled.

Yes, I believe all of my "fixes" lasted for a short while, as in perhaps a week or two. Usually my frustration with it had me cease from using it temporarily. Then I'd use it again, and all seemed fine. That mod just konfused the hell out of me. Still does, as I REALLY DO like that darn thing!

DNA 75 - HCIGAR VT75 nano/Resistance problem

That was extremely interesting. I really had no idea that so many suffered from so many probs with the Nano. I could not/will not/can not even think about the remedies tho. My general vape repair tools only include a nail file and a toothpick.

So, like DPL, mine sit on my museum stand. I have wrestled with selling my red one for awhile now, but with the issues it seems to randomly present, I don't know that I can do that. I suppose if someone came along with the talents to do these mysterious (to me) repairs, I might consider it. That battery door alone is enuf to drive one to the drink brink.

Opti-Miss, me. Let's see how the electrician's grease goes.

I'd say yes to all here, Dave. Very yes.

 

[DaveP]

MyVaporStore has it on sale for $49.95. It's out of stock, though. That may mean it was discontinued (possibly for high return rates) and won't be back. I'm on the notify list for when it's back in stock.

 

[DPLongo22]

@Steamer861 - either my luck with the VT75n is terrible, or yours is fantastic.

Just over 24 hours, back to bouncin'. Whatcha gonna do... (rhetorical).

Kat's running her black one now, with just a regular cleaning. Since the results (for me) were the same as this time, I don't think the di-electric grease is the kicker.

I believe that, in our case at least, our mods have a screw loose. In retrospect, and considering the two owners in question (the she and the me), I do believe that's somewhat appropriate.

We'll see how hers makes out, eh?

 

[Katdarling]

Keep that popcorn poppin', sweets.

Screw loose, appropriate to the he and the me, yes. VERY.

Ok, day two of my own resistance bounce experiment has not brought me a smile. I vaped my black Fred (Nano, for those not in the know) all day yesterday and it jumped from 1.38 ohms all the way to 1.37 ohms. Not too shabby, thought I!

This morning, it awoke at 1.50 ohms.

I'll keep tracking it for awhile, but methinks it's a rhetorical and fantasy-filled process in my opinion.

It's sad. I adore this little thing.

Dear Diary,

Day 3. 1.68Ω.

See you tomorrow,
