And no, their service is not supported by ads - You have to pay for a subscription. Consumer Reports needs to be mentioned more IMO. Because even on reddit, there are companies that offer advanced stealth-like astroturfing campaigns for products/services.
The counterargument is that Consumer Reports could be intruded by corporate shills, but their reputation is solid and they've been around for a long time.
We can do better than CR - but right now, afaict they're the best we have.
My go-tos are sites like Wirecutter, where it seems like the hit to their reputation would be too high to be blatantly bought-out, even if they'll generally only hawk products that can be bought on Amazon or other sites that give them affiliate money. They're not always perfect, but I trust that they're trying to do what they set out to do.
The main issue with most review sites is that they're kids. Companies like NYT/Wirecutter don't want to pay old men that are experts in manufacturing. They hire kids with little life experience to review something like a washing machine. They haven't had 2 or even 1 washing machine in their entire lives. They wouldn't even be capable of doing a teardown. Let alone identifying which parts are quality vs not.
Unless of course your main qualification is not trying to find something that is built to last. Which is the hardest thing to get these days. Finding garbage like electronics and software is easy. Everyone wants to sell you software rather than high quality manufactured goods. And I want the least software possible as I'm very anti-technology for a software developer.
My research sources would be roughly in this order:
1. Consumer Reports (teardowns, can't beat this method. You pay them directly, if interested in least conflict of interest)
2. Wirecutter (good for a free source, but puts near-zero weight on reliability)
3. Amazon reviews (can find some old timers reviewing there but always keep in mind that most people aren't very intelligent. They maintain nothing and won't skim a manual)
4. Reddit (a lot of zero life experience kids on that, meaning generally anyone under 40)
5. Then whatever else you can find on the web
Looking past the bargain and location aspects, this site is super useful for understanding products in greater detail
