Poster child of the rotten ratings right here:

https://www.amazon.com/gp/product/B01B6ZHV7C?th=1 (rated 4 stars but 87% of reviews are 1 star)

I just looked into why that is the case and if you hover over the little dropdown carrot for the "3.8 out of 5" you see this:

Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.

So a product would just need a small percentage of 5 star reviews in the beginning of the review period.
