I cracked it open and looked at the connections. I must say that the solder jobs are piss poor and I will most definately suck those blobs out of there and flow something a little better. I also believe that my assumption may be correct about the ground and wonky resistance readings. Looking at the top portion of the box there is screw that looks like it has a wire soldered to it. I hope there is a lug underneath that screw, but at first glance it appears that the wire is soldered to the screw itself.

I just want to warn you that if you remove the battery sled (you have to remove the QC sticker covering one of the screw holes) you WILL void your warranty. It is up to you on weather you are okay with that or not, I just thought you should know.

Hyuk. My elev8 is off to service. But the one I got from
Wetvapes is still working like a champ.

50-50. I'm doing good In life

Let us know how that goes at elev8. I sent mine back to asmodus since elev8 wouldn't take it back after I had it in my hand for 5 mins and the 510 connection wasn't fitted in the device. I contacted them and they said it was a warranty issue and to send it to asmodus.

The guy is talking about redoing the soldering. I don't think he's worried about the warranty.

Yes I know what his plans are, I quoted his post which means I read it. Some people may not know what does and does not void a warranty that's why I said I was just letting him know.

Has anyone had any issues with the device shutting off when being set down onto a hard surface? Mine has been doing that lately and I was wondering if anyone knew of a quick fix for it. I am not slamming it down by any means but when it was set down in most any fashion it seems to shut off. No serious complaints past that!

Maybe pull the spring up a bit?

Well I cracked open my box this evening and notices a few things of concern.

1. The ground is indeed soldered to the screw at the top of the inside of the unit. This is a piss poor connection and will more than likely fail in due time.
2. The positive and negative connectors of the battery holder seem to be oxidized or something like that. They could use some cleaning with contact cleaner or maybe some polishing with 2000 grit sandpaper.
3. Most of the larger solder connections seem to be oxidized. I am guessing that a poor quality solder is used to make these connections, or a correct flux was not used to clean the connections before soldering (or both).
4. The SMD connections to the internal circuit board seem to be of good quality and I don't think there will be any component connection issues.

I the next few days/weeks I'll correct the deficiencies and document for general knowledge of this thread.

Holy cow man , what are you doing lol. Just my opinion but i would leave well enough alone , until we start to have failures due to the above issues you mentioned why F with it . On the other hand if you insist on messing with it , yes, please do document so idiots like myself will know what to do if it does go haywire.

Thanks

I am doing this because I do not trust the build quality of the device. For some strange reason it has been tuning off with just a slight tap on either the side or bottom. I stretched the spring a little and that may have fixed it. When I first inspected the device the "dirty" looking positive and negative connections had me worried about proper current flow at high loads.

Also I took interest at some of the issues I had noticed about wonky resistance readings. The ohm calculations are all handled by software and I don't think it is the problem. That leaves the connections. The ground was my first guess as it is connected to a damn screw.

For science?! Yes. I am an engineer (electrical) by trade and it drives me nuts to operate a poorly constructed product. I have a lot of experience with Micro and Miniature level electronics repair and have to regularly inspect solder connections under a microscope. Needless to say I don't like bad solder joints or any type of corrosion when it comes to electronics. I have all of the tools to do this repair at my immediate disposal so I just suits my "comfort factor" if you will.

This device will more than likely fail when I need it, and I don't want that. Simple fixes are needed to satisfy my anxiety of being out and about without a vape. I usually have my egos and iTaste V3 around me, but I don't really like carrying them around all of the time.

I actually thought of making my own mod but the time and money spent would not be worth the hassle unless I could sell them, and there comes the liability issues. In the end it is more feasible to purchase a device. It would be cool to do, but there are probably teams of folks working on these devices and they have most of the bugs worked out already. I would be starting from scratch and as anyone with knowledge of microcontrollers and programming knows that the initial code comes fast in general and the testing and debugging is what takes the most time.

Yes I have the black and my finish is coming off already in a few spots. The roughest thing mine is exposed to is the inside of my pocket, haven't dropped it, haven't had juice leak on it at all, and I don't put anything else in the pocket with it yet the finish is coming off.

It doesn't bother me at all actually I wouldn't mind if it went down to bare aluminum altogether. I can see it bothering some people though.

PS
As the paint starts to wear off it looks "sparkly" in that spot, almost like highly metallic flake paint, more so than the rest of the paint. This is simply because the paint is very thin and you are starting to see the bare metal underneath.

The paint really is garbage though to wear off this fast. They could have just colored the outside with black permanent marker, it would have lasted longer and actually been black.
I have black also and I put it in the pocket I keep Get A Fool Up Off Me in and it scratched to .... now

In all honesty, in regards to atroph's comments, The 2 major connections you mntioned should not be of concern. The ground is indeed soldered and screwed on the upper half of the device, and the connections for the batteries are indeed a bit tarnished. However, in weeks of use, I havent seen any issues. And I've cranked it to 50w on a 0.7 build. No issues, no over heating.

So I'll keep with the simple philosophy of "IF It Aint Broke, Dont Fix It!" ^^

They actually responded? You're lucky! I've been calling, emailing, and texting for a week with no answer. Mine was fine, then put it on nightstand for the night and come morning, wouldn't power on, or fire. They state that THEY WOULD HANDLE WARRANTY ISSUES, guess thats not true... Hope they have the courtesy of at least getting back to me...
