Vuitton do use good materials and have a lot of quality control.

Isn't that also one of the justifications for paying Fluke prices?

I doubt they'd last as long as my work clothes in the same environment.

As to whether Pomona make Brymen leads, I thought I had read that somewhere, but can't remember where. Certainly I could easily be mistaken on this, and if anyone has firm knowledge on the subject I will be happy to stand corrected.

However, claiming that Pomona and Fluke leads have no differences is disingenuous. That's like claiming all Skodas and Audis are the same because there are some common parts, and they are part of the same corporation. Or Volkswagens and Seats, pick any two from the VAG corp.[/color][/size][/b]

So after all this talk about data, rumors from the internet are also a data point..

You were prepared to believe that Pomona makes probes for Brymen because of your cognitive bias that only brand name companies make good products, and that others only make cheap shit. So if Brymen makes something good it is because somebody else makes good probes for them and somebody else designed meters for them or they stole the design....

I have, during the years, tried all kinds of meter cables. Worst ones were very expensive Fuke modular set (150€ set, tips and accesories were fine but cables were absolute crap, breaking all the time. Replaced cables many years ago with UNI-T made ones and they are working perefectly since). And I was VERY gentle with the cables, because they were very expensive, lab use only... Another ones that are crap are tiny Pomona needle types.. They have occasional bad contact, and wires are annoyingly thin, if you work over the device or inside, they keep getting tangled and keep getting hooked to stuff all the time.. OTOH Probemaster needle tip pogo types are fantastic..

And Pomona and Fluke probes are literally SAME. There is one factory (Pomona ) that makes probes for both brands (and Pomona sells to others too, like Keysight). There is no separate Fuke DMM leads facility. Pomona factory is that.
There are some probes that are only Fluke branded, with visual design that goes with it.

Welcome to the corporate efficiency optimization...

And you are exactly wrong about Skoda, WV, Audi and Seat. On the most of the range ( if you discount high end special cars that are only sold under premium brands part of the group) commonality of parts is pretty much more than 80%.
They are (except visually, outside and in the cabin) pretty much same cars, for the most important parts (whole motor group with transmision, chassis platform with suspension, security platform, etc).
And funny enough, components being mostly the same, the care and pride to assemble them makes a difference..
Our Czech friends take great pride in their legacy, and in the whole VW group, Skodas are most reliable. More than Audi..

Corporate assholes know very well how people are blind when you slap on a big brand. They will happily sell you same product quality as common products, and will charge you 10x more... Because big brand is worth it.
Or is it?

This is all moot. You can never trust a specific brand or that any item they sell will be invariant over time. You have to buy something and inspect and test it either through sampling for large sets or validation for single items and easy to test items.

I'm sitting here going through 2080 resistors at the moment doing pass/fail limit testing with my 34401A :D

No, you're ascribing motivations that simply don't exist. I said I thought I had read it was the case, but couldn't remember where, and might simply be mistaken (or misremembering), and was happy to be corrected by someone with firm facts.

Just one Pomona factory makes all Fluke, Pomona, and some Keysight leads? Do you have any firm knowledge of this or are you guessing? I am curious as to how they produce two types of TL71 (good ones and bad ones) in the same factory without getting confused.

As for the VAG point, you are telling me I am wrong because I am right? This is very confusing...
