Analysis Details
Fail Unverified Purchases
10 of the 320 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 1.4 while the verified purchasers have rated this product an average of 3.8. 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
49 of the 320 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 2.9 while the reviewers who have posted more than one review have rated this product an average of 3.9. 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.
Take-Back Reviewers
23 of the 320 reviewers have had at least one of their past reviews for another product deleted. The Take-Back Reviewers have rated this product an average of 4.3 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 3.7. 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
-
- 39%
- 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 124 reviewers (or 39%) are within an overrepresented participation group. These reviews have rated this product an average of 3.3, 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 Deleted Reviews
We discovered a total of 1 deleted Review for this product, with an average rating of 5. Even though deleted reviews don't affect the average rating, the fact that action was taken to delete reviews raises some red flags about the integrity of the reviews for the product as whole.
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.
Pass Rating Trend
-
- 4%
- Created over 3 days
We counted 320 reviews for this product over the span of 947 days, an average of 0.3 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 3 or fewer reviews on any given day.
However, we see the following 3 days exceeding this threshold:In total, we found that 12 reviews were created on just 3 days. This is within an acceptable range and it does not appear to be significantly affecting the overall rating for this product.
Pass Word Count Comparison
-
- 27%
- Have an overrepresented word count

We see the following 1 group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 87 reviews (or 27%) are within an overrepresented word count group.
