There's a somewhat pervasive idea that advertising and brand recognition are coercive tools that will ultimately die out, replaced by better objective information about products. I'm kind of partial to this idea myself. But increasingly we seem a long way from achieving this. Amazon reviews have become such garbage, I've fallen back to pretty much relying on name brands as my placeholder for product quality. There's…
I've fallen back on a combination of brand, country of manufacture, price, and to some extent if the company has its own retail presence outside of Amazon and other online or meatspace big box stores. For example...
If the brand is good, the item is expensive, but it's made in China and sold on Amazon, I try to avoid. There's some risk it will be money wasted on something that will last just 3-6 months.
Conversely if all of the above are true but the item is cheap, I'll buy it from Amazon, enjoy their fast delivery, and simply build into my expectations and budget that it will need to be replaced in 3-6months. This is what I've come to with headphones, for example.
On the other hand, if the item is made in (not just designed in, but made in) the US, Japan, Korea, Germany, or some other Western European countries, then it matters less what the brand or retail venue is. For example, buying a room fan, power tool, or similar, I'll look for one with a motor made in US/Japan/Germany/etc.
These are the best signals I've found to be available atm.
