I did infact make a post about lines going through the screen after just a week of use, and I would have contacted my vendor but unfortunately I was not able to make time to do so. At the time I was overworking everyday and basically passing out as soon as I got home just to repeat the next day, but my Sigelei still worked, so I dealt with it. The finish started to rub off to the right of the screen but I figured I'd just get a wrap for it. And then out of left field it just stops responding to the button but every few clicks, no user error, nothing. I was willing to continue using it despite the messed up screen and shoddy finish, but now that it barely works I guess I am backed up into a corner with options to do with it so I will be contacting my vendor to see if they can do anything.In another thread you reported problems with this sigelei during the second week of use. You said that a line appeared under the text that appeared on the OLED display. Given the relatively short warranty provided with most Chinese made APVs it is important to contact the vendor if any problems develop during a warranty period. Symptoms are symptoms.
I wrote this in another thread a couple of days ago. It pertains to anyone who buys a Chinese-made APV.
The Sigelei Zmax V3 Telescopic and the Provari are both bell and whistle-laden APVs. I was looking at both last month when I wanted a new APV to celebrate a year without smoking.
I chose the Sigelei. Accuracy on both APVs is too close to call a difference.
The Sigelei offers 510 and eGo threading, the Provari doesn't.
The Sigelei Telescopic will handle 18350, 2x18350, 18400/18500, 18500 and 18650 batteries without expensive tube extensions or buying a separate mini model. Telescopic battery tubes means battery versatility when you want it at much less cost.
The Provari has a far better warranty, no doubt about that. As to which APV is more durable only time will tell. Anyone who says the Provari is more durable is just guessing. The Sigelei Telescopic hasn't been in use for a year.
Not all Chinese-made gear is junk. I used my Smoktech E-Power 14650 every day for 18 months. It never died. It's still my back-up rig.
With all that money I saved with the Sigelei I upgraded my battery supply, carto tank, and carto stash. I still had a lot left over.
Chinese gear will have a higher defect rate. I got around this by using the Sigelei heavily during the shorter warranty period and keeping a very critical eye on performance. I was ready to return it quickly if any problems arose. I operate on the theory that if an APV doesn't have problems during the first weeks it's usually good to go for a long while.
Besides, the Sigelei Telescopic flat top looks a lot better than a Provari.
I am looking into answers regarding the six month guarantee that appears in the Sigelei Zmax User Manual that came packed with my Sigelei Telescopic. I have not experienced any problems with it to date that I can't account for by user error, but I want some more specifics on how to use the guarantee. I will pass along anything I can learn.
The Sigelei guarantee:
“Products are guaranteed for six months from the delivery date. we will not guarantee products that have been damaged through improper use or intentionally damaged.”
I assume that this guarantee applies to the Sigelei user, and not the vendor as it appears printed in the User Manual. Stay tuned.
