But once there are 500 reviews on a product it basically gives you that confidence.
This isn't a troll comment. Ben Thompson makes the argument that the reason why EBay, AirBnB, and Uber work is because you basically are replacing the trust you had in a brand with the trust you have in community reviews. He calls it 'Aggregation Theory'. I find it rather compelling to explain why these types of marketplaces work.
Problem is another supplier can claim to sell the same item and benefit from the positive reviews. I've seen a lot of this with unbranded items like USB chargers for cars.
Bingo. You always need to check the most recent reviews because of this: a solid history of 5000 5-star reviews is meaningless if the past 200 are 2-star reviews saying, "Not what I expected".
Exactly. And then you look up and you're 20+ minutes into skimming reviews in order to buy a $3 care remote battery or cable and wondering why the hell you didn't just drive to target / walk over the apple store because you'd be done with the errand by now.
I ran into exactly this earlier today. I needed to get a new Macbook charger and just buying one directly from the Apple store nearby was faster than (as I first attempted) trying to find one on Amazon without "this is actually a counterfeit imitation" warnings in the reviews.
At this point I just flatly don't trust Amazon anymore for small electrical devices, because there's too much of a chance (even for things labeled with brand names) that it's actually a cheap knockoff that will short-circuit and set something on fire eventually.
