Analysis Details
Fail Unverified Purchases
161 of the 1,020 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 4.5 while the verified purchasers have rated this product an average of 4.1. 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.

The One-Hit Wonders have rated this product an average of 3.5 while the reviewers who have posted more than one review have rated this product an average of 4.2. 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 Reviewer Participation
-
- 58%
- From reviewers with an overrepresented participation
We see the following 1 participation group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 594 reviewers (or 58%) are within an overrepresented participation group. These reviews have rated this product an average of 4.3, while all other reviews have rated this product an average of 4.0. 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.
Warn Word Count Comparison
-
- 34%
- Have an overrepresented word count
In the graph above, we can see the distribution of review word counts for this product and the expected distribution for this category. We see the following 1 group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 343 reviews (or 34%) are within an overrepresented word count group. While this is more reviews from overrepresented word count groups than we'd expect to see, the discrepancy in ratings between reviews with overrepresented word groups and all other reviews isn’t significant enough to rule out the possibility of it being due to random chance.
Pass Rating Trend
-
- 2%
- Created over 4 days
We counted 1,020 reviews for this product over the span of 1,649 days, an average of 0.6 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 4 or fewer reviews on any given day.
However, we see the following 4 days exceeding this threshold:In total, we found that 25 reviews were created on just 4 days. This is within an acceptable range and it does not appear to be significantly affecting the overall rating for this product.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
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.
