Analysis Details
Fail Unverified Purchases
1,066 of the 1,843 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 9.2 while the verified purchasers have rated this product an average of 8.8. 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 Brand Repeats
Brand Repeaters
497 of the 1,843 reviewers have reviewed other products for this brand. While this is more Brand Repeaters than we'd expect to see, the discrepancy in ratings between the Brand Repeaters and non-repeaters isn't significant enough to rule out the possibility of it being due to random chance.
Brand Loyalists
438 of the 1,843 reviewers have reviewed multiple products but half or more of their reviews are for this brand. This is an excessively large percentage of Brand Loyalists which may indicate unnatural reviews.
Brand Monogamists
335 of the 1,843 reviewers have reviewed multiple products, but only for this brand. This is an excessively large percentage of Brand Monogamists which may indicate unnatural reviews.
Fail Suspicious Reviewers
One-Hit Wonders
762 of the 1,843 reviewers have only reviewed this product. This is an excessively large percentage of One-Hit Wonders which may indicate unnatural reviews.
Never-Verified Reviewers
743 of the 1,843 reviewers have never written a verified purchase review. While this is more Never-Verified Reviewers than we'd expect to see, it does not appear to have a significant impact on the overall rating.
Take-Back Reviewers
581 of the 1,843 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 9.4 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 8.9. 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 Reviewer Ease
The ease score is the average rating for all reviews that a given reviewer submits. The average ease score for reviewers of this product is 9.1, while the average ease score for reviewers in this category is 8.8. 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.

Fail Phrase Repetition
Reviews that contain one of these phrases are NOT necessarily devalued; read more about how this test works here.
63 of the 1,843 total reviews for this product use substantial repetitive phrases between them. These reviewers have rated this product an average of 9.5 while reviews without substantial repetitive phrases rated this product an average of 9.0. 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 43 deleted Reviews for this product, with an average rating of 8.8. 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.
Warn Rating Trend
-
- 38%
- Created over 55 days
We counted 1,843 reviews for this product over the span of 1,066 days, an average of 1.7 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 7 or fewer reviews on any given day.
However, we see the following 55 days exceeding this threshold:In total, we found that 697 reviews were created on just 55 days. This is an excessively high number of reviews submitted on these high volume days.
Warn Reviewer Participation
-
- 87%
- 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 1609 reviewers (or 87%) are within an overrepresented participation group. This is an excessively high number of reviewers in overrepresented participation groups.
Pass Word Count Comparison
-
- 28%
- 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 507 reviews (or 28%) are within an overrepresented word count group. This is within an acceptable range and it does not appear to be significantly affecting the overall rating for this product.
