Except that there isn't a good way to distinguish between something that is expensive because it has quality construction and something that is expensive because it is a brand name.
Searching for information online is nigh-useless due to aggressive SEO on the part of advertisers. Sometimes I can get lucky and find an enthusiast forum, but those are harder and harder to find.
Online reviews in general are effectively anonymous. Amazon reviews might not even be the same manufacturer, let alone the same product. Newegg lists different firmware versions under the same product ID, so compatibility reviews are useless.
The best thing I've found is to reach out to a group of friends and hope that one of them did the research previously, or can at least steer you towards/away a brand. This doesn't scale, and any approach that does scale is at risk of being overwhelmed by advertisers and other bad actors.
This thing is built like a fucking tank, it will never ever ever fail.
Compare that to the same model sold outside of Japan, and it's most likely made in Indonesia and the quality is nowhere near.
Except being built like a tank, Japan made one also vibrates less and more comfortable to use.

He's a private dude, but I think his wife is french-canadian and he's at least bilingual. And from what I've gathered he has to have done some kind of mechanical engineering for a LONG time. Dude knows his stuff about anything mechanical.
His teardown of the Juicero is pure gold: https://www.youtube.com/watch?v=_Cp-BGQfpHQ
It's an amazing insight into a startup with endless amounts of money, bunch of really smart people, but no real business model. =)
Anything "professional", "military", etc. comes with the potential downside of it being someone's job to maintain and service it. Qualitative differences usually come with trade-offs - and if it's not your job, it might not be better to try.
If I break something or need more bits, I can always go back years later and get a matching piece.
I'm talking about Grand Maitre series [1], which are "Made in Germany under supervision of Victorinox" and are forged steel. They're nowhere near €35. I have a 15cm Grand Maitre Carving/Utility knife, and that thing's sharpness is scaring me sometimes. It's virtually equal with another handmade, hand forged set I have, and both blades hold their edges extraordinarily well.
OTOH, America's test kitchen has found that these €35 Classic knives has some extraordinary steel for their price, under an electron microscope. I was unable to find the exact video, sorry for that.

HiFi gear is one of them. My CD player (from Yamaha) and speakers (from Heco) were cheaper when compared to other brands, but they're at least equal with their qualities, and they proved themselves over the years.
Similarly, if I can get 90% quality of a Wusthof by getting a Victorinox Grand Maitre, I'm OK with that.
I've also found out that technology has improved dramatically in certain categories. I've bought an entry level Sony BT headphones (Sony WH-CH510), and the sound quality for that price is unbeatable. I have much better headphones, but for something which I can grab and go, it's unbelievable. I had to pay thrice the price for that sound quality 10 years ago.
Paying a bit more for a better item which can be repaired or serviced for a very long time makes it cheaper in the long run in my experience, because you buy it once and for life.
I love "overkill items for everyday life" point of view, but it comes with trade-offs for noise, ergonomics, size, replaceability and such. You can get a very good blade from Victorinox or Leatherman. If you fancy good steel, you can get a high end, forged German steel Victorinox chef knife and use something frighteningly sharp and handsome at the same time.
If you want a good heater, you can pay twice the price and can get a Fakir Hobby premium space heater and can use for 30+ years (we have two).
The list can go on.
