I have to disagree with you on this one, fairmana. I'm looking back over a lot of posts on this thread I just don't see many recent display shifts due to over-tighened tubes. I see a few that resulted from drops. I own two V3s and a V5. The oldest V3 is 14 months old and that one will misfire maybe a couple of times a day... not enough to warrent repair yet. The others don't misfire, ever. None of the displays have shifted in my devices.

The switch on the V3 and V5 is one of the weak links but we haven't seen nearly as many switch problems reported on these Sigeleis as with the SVDs, for example.

Keep in mind that these sigelei APVs are priced in the $40-$55 range, tube alone. These are not $150+ rigs and cannot be expected to perform as such. I am the last person to pretend that they do.

That's quite alright Yzer. We each have our own opinions and different expectations, which is one reason I enjoy this thread. I have no idea how you put up with that misfiring button though. IMO a button that misfires a couple of times a day is enough to warrant a button replacement, and that is exactly what mine have done when I decided to replace them. I just don't have the patience to deal with a misfiring button and to me it has already "failed" if it doesn't fire consistently 100% of the time. I need to feel confident that when I press the button it's going to fire.

Back to the original topic, I have to call it like I see it from personal experience with this device. I happened to purchase both of my V3's at the same time you bought each of yours (original and later versions), and I've had the opportunity to get 1st hand experience with an additional 6 devices owned by close friends and family (most are the latest versions). I'm not considering the additional V3's I've repaired for people that have PM'd me, because that wouldn't be fair (they're obviously bad or they wouldn't send them to me to fix). I've likely held and worked on more V3's than most people, and I don't mention it to boast but rather to underline that my opinion is based on a larger group of V3's than most people have had the opportunity to come into contact with, and that should count for something.

I realize that the posts in this thread could be considered a group of V3's or V5's that we can pull data from, but I doubt that everyone would post a comment who is experiencing problems. I would recommend caution when basing the failure rates of a device purely on thread posts because I just don't feel it will be accurate. People don't always have the time nor the inclination to share their personal experiences (if they've even bothered to search the web for a solution). Another possibility that should be considered is that individuals with issues could have found this thread, confirmed their problem (since there are enough posts on screen shift and button issues), and simply tossed the device aside (it's only worth $45 bucks, right?). People may simply decide not to post about something that's already been posted to death about, especially since several of us have contributed solutions to these problems already. Ex. "Yup, my V3 is broken, it's a common issue according to what I'm reading in this thread, so why bother registering as a member of ECF just so I can post and tell a bunch of V3 owners what they're already aware of". I'm just saying... just because we haven't seen many complaints in this thread lately is not a reliable way to judge that failure rates are lower than they were before. If we really want to reliably collect that sort of data then some sort of poll is probably a better way to do it.

I completely agree with what you're saying in regard to expectations vs. price, and I hear you loud and clear that these are not $150 devices and no one should expect the same kind of reliability from a $45 device. I've always agreed on this point and as I've said before I still love them and use them exclusively. That being said, I've had to eventually fix and modify both of them to fix these flaws so I could get the reliability that I desire (shifted screen and button failure on each of these). More accurately, I've eventually needed to do this for all my friends and family that own them as well.

My main point in all of this is that anyone who is thinking about buying one should have as much honest info as possible to base that decision on. I think this thread continues to be a great place for people to get that info and discuss these devices. Nobody said that we always had to agree on the facts. :)

I don't think we are going to get any statistically accurate failure rates from posts at ECFs. Any polls posted at ECF would be statistically worthless as well. No one can assume that all Sigelei V3 and V5 owners read or post at ECF

If somebody wanted to do the homework I suppose that every Sigelei V3/V5 owner who ever posted on this thread or anywhere on ECF could be PM'd with a questionnaire regarding lifespan and reliability of each of their devices. I don't know what kind of response anyone could expect from that considering people change email addresses, quit vaping, die, etc. On top of that, any returns would have to be compared to similar information gathering attempts for other APVs to put the results into perspective.

Everyone must establish performance parameters on an independent basis. If the brakes on my WRX refused to work once during the dozens of times I use them on a light driving day I would look into the problem and fix it immediately. If a V3 misfires three times out of 700 operations in a day I may not want to sweat it very much.

I have the switch replacement ready to go. Since I have two Sigeleis that work flawlessly I may work on the first V3 sometime soon, maybe not. I have a lot of maintenance to do on the boat this season and I've just started.

One question for fairmana... of all the Sigeleis you have handled or worked on where were they purchased from? Mostly from one US dealer? Mostly FastTech? From all over the place? Is the vendor a factor?

Thanks for posting that, VapieDan. It's not a very accurate attempt at a Sigelei clone but it does have a vague resemblance to the real thing.

There are so many things wrong but the shape is close. Never seen one that similar. Took me by surprise.

The first one I purchased (original version) came from Vaporheads.net in April of 2013 ($68.99). I saved a few bucks because it was a "scratch and dent" V3 because of all the complaints they got regarding the crooked OLED screen that Sigelei was shipping out. I really couldn't care less about the screen at the time but I corrected it on a whim the first time I took it apart to replace the button. I purchased my latest version V3 last Christmas from DesertVapes. Everyone else I know that owns a V3 (friends and family) all got theirs from Desert Vapes since they seem to consistently have the lowest prices on them. Those that have been sent to me for repair I couldn't say since I never asked.

Your guess is as good as mine if its a vendor issue, but that wouldn't be my initial impression. You'd assume that vendors put in their orders to Sigelei in quantity and Sigelei just fills them. I don't see how a vendor would have any control over quality considerations from the factory unless something weird was going on such as selling "refurbished" V3's as "new stock" or something along those lines (reason for lower prices?). I'm just thinking out loud and have no reason to suspect that, so please don't anyone accuse me of starting any unsubstantiated rumors against an otherwise decent vendor. :) I'm sure we can look back through this thread and prove that people have had similar issues from multiple vendors.

I tried to find more info on that EhPro ZMaz clone. I was able to find a YouTube video comparison between the Sigelei Zmax and the EhPro T-ZMax, but unfortunately it's in German. Regardless, I watched in anyway to see if I could catch a glimpse of the menu similarities. At 6:30 in the video the guy goes through the menu options of the EhPro T-ZMax clone. There are a few minor menu differences but the similarities are striking and are almost identical. One example is their use of "Batte" for "Battery" just like in the V3 menu. Something I'm not too keen on is the smaller button located on the side. I read on another forum that the internal button is smaller on the circuit board than the one used in the Sigelei and is also prone to early failure. Apparently that button isn't as easy to find if it needs to be replaced (not sure how true that is but that's what I read).

Jeremy, I have no idea what any of that means, likely because I don't own an RBA and I'm just not familiar with the lingo. However, you've piqued my curiosity regarding what a "posted" RBA and a "nores" connection are. It could be something some of us might take an interest in (possibly to make a better mechanical connection on the V3/V5?). Can you provide a little more info?

I mean a rebuildable atomizer, they have screws that solidly attach the wires to the post connections.

You get no fluctuation with these connections.

Rebuilding a clearo can have fluctuation, and a gg odessyus uses a no resistance wire connection.
This is a nores connection

This is the v3 in action with stacked 18350 parallel 32 at 1.5 ohms & about 5.8v. This is at just shy of 1 second
