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.
