High bias found in Amazon reviews of low-cost or free samples

I use this system for my own reviews:

  • Five stars: Perfect, would definitely recommend
  • Four stars: Good, but with some minor drawbacks.
  • Three stars: Not as advertised. Might fit your needs, might not.
  • Two stars: Bad.
  • One star: Unredeemably bad, in ripoff and scam territory.

In practice, I see this:

  • Five stars: Vacuous gushing praise
  • 3 +/- 1 stars: Some honest thought went into the review
  • One star: Usually unwarranted hate

I like the three star reviews for this reason. They typically go into more depth describing the product and its differences between what’s advertised or what’s expected. It’s far more informative to read reviews from someone who knows what they want and can articulate that.
