It is so much more difficult than it used to be to get trustworthy information about the quality of products. Seems like you have to already know of a hobbyist turned youtuber/blogger who has ideally done deep dives into a class of products or at least some relevant product reviews (or has a large subscriber base with active discussion threads).
Even trying to find such a content creator on the fly can be dicey since so many of them are doing paid reviews or at the very least are sent free products + incentives. That, or get lucky googling site:reddit.com/r/[subreddit] [product] to find a thread that isn't too recent, isn't overrun by shills and isn't woefully out of date and full of deleted/overwritten content.
The availability of that information is probably worse than ~10 years ago, but still better than any time in the past before that.
Another problem is that there are just too many products these days. 40 years ago someone might have 5 options for a vacuum cleaner, period. Someone on the internet today might have 500 options. It's just information overload. Someone who really cares to, might go through the 236 options that Consumer Reports has tested [0]
But most people aren't the type of people who would spend a half-hour arguing about consumer product quality on the internet. Most people aren't willing to spend any time to evaluate their options for relatively small purchases beyond the immediate moment of purchase.
