I used to be part of Amazon’s program where you get free items to review. It’s even worse than people think.
I left negative or neutral reviews that just don’t appear on the listing, or the seller will contact you directly offering you more free things to upgrade your review, or they’ll just relist their crappy broken product and hope the reviewers write positive reviews (a lot of reviewers would just get free stuff and then write something positive without actually testing it).
Amazon reviews are totally unreliable, and even those sites and extensions that try to determine if a product’s reviews are legitimate aren’t very effective.
I just ask people directly to share their experiences now or create a post on Lemmy because it’s so bad.
