Mine is as stable as it an be (one count). Bought in 2021, IIRC.
From my testing, Brymen has proven to be right there with the name brands. Not only some of the most electrically and mechanically robust products on the market but also are withstanding the test of time.
As someone who sells a lot of Brymen's, I can attest that they have a noticeable non-zero long term failure rate. It's not high, but it's certainly not zero.

But we don't have any data for Flukes to compare against.
I've certainly seen plenty of people here showing off about how they just sent their Fluke back and got a new one in exchange.
(but I can buy three Brymens for the same money with 99.9% chance of it lasting longer than me)

I reviewed the Fluke 289 about a year ago, you can see the stability in my testing:

Has anyone dug into why their custom silicon suffers these failures? Firmware corruption (I feel if it were this there'd be a lot more cases)? Ionic contamination of the die? Contamination or damage of the die during manufacture? Charge carrier migration or accumulation? It might be nice to have a failed one decapped/X-rayed, to see if there's anything obvious.

Yes as the famous fluke limited lifetime warranty (10 years) or the 1 year warranty on their cheaper lines is not transferrable. So if you buy a used fluke no matter how new, you're out of warranty. This goes for pretty much all brands warranties though
rands for a lot of users, but the two products are not equivalent as to service and warranty, at least in the US. YMMV and I think the situation is probably almost reversed in the EU.

We don't know.
BTW, the Brymen processor is not custom, it's a known brand. I'm under NDA so I can't tell you which one.
What's that enormous low resolution meter?
