Make Sure the Descriptions Match
The first thing you should do when looking at a product on Amazon is to check whether the reviews actually match the item. If there’s any discrepancy between the reviews and the item itself, it’s likely a sign of some sort of scam.
It appears that scammy sellers on Amazon will take a well-reviewed item and switch out the actual product and description, leaving unrelated-but-high reviews. Amazon undoubtedly has policies against this, but a scam product may slip through the cracks.
