Analysis Details
Fail Rating Trend
-
- 98%
- Created over 2 days
We counted 723 reviews for this product over the span of 28 days, an average of 25.8 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 43 or fewer reviews on any given day.
However, we see the following 2 days exceeding this threshold:In total, we found that 710 reviews were created on just 2 days. The reviews on these high volume days have rated this product an average of 5.0 while reviews from other days have rated this product an average of 1.9. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Fail Unverified Purchases
710 of the 723 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 5.0 while the verified purchasers have rated this product an average of 1.9. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Unverified purchases may be the result of Kindle Unlimited readers, buyers who didn't pay full price, or reviewers who did not purchase the product at Amazon. Read more about our Unverified Purchases test.
Fail Suspicious Reviewers
One-Hit Wonders
4 of the 723 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 2.0 while the reviewers who have posted more than one review have rated this product an average of 5.0. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Never-Verified Reviewers
710 of the 723 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 5.0 while the reviewers who have written at least one verified purchase review rated this product an average of 1.9. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.
Single-Day Reviewers

The Single-Day reviewers have rated this product an average of 5.0 while all other reviewers rated this product an average of 1.9.

The average ease score for reviewers of this product is 5, while the average ease score for reviewers in this category is 4.3.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
- We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
- We have no information on reviews that were never published in the first place.
- We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.
