You'd think that Amazon would have some technology similar to FakeSpot's by now, but I'm not convinced that they do. I bought a product that had the special "Amazon's Choice" label on it that turned out to be a dud. I looked up the product on FakeSpot just now, and FakeSpot (correctly, I believe) identifies the reviews on that product to be unreliable (grade level "C"). Just a single anecdote, but it's clear to me that there's a ton of room for improvement on Amazon's part.
Another strange thing about the "Amazon's Choice" label is this: I've seen a product get that label in part due to a low number of returns ... but the seller doesn't accept returns! That should be a con, not a pro.
As you can probably tell, I have not been happy with the results of following Amazon's product choice advice.
