Analysis Details
Fail Deleted Reviews
We discovered a total of 35 deleted Reviews for this product, with an average rating of 9.9. 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.
Fail Unverified Purchases
350 of the 609 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 9.6 while the verified purchasers have rated this product an average of 8.6. 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 Sample Reviews
34 of the 609 total reviews for this product mentioned the word "sample" within their review. The reviews that mention the word "sample" have rated this product an average of 9.7 while reviews that don't mention the word "sample" have rated this product an average of 9.1. 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.
Fail Brand Repeats
Brand Repeaters
365 of the 609 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
283 of the 609 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
200 of the 609 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
158 of the 609 reviewers have only reviewed this product. While this is more One-Hit Wonders than we'd expect to see, it does not appear to have a significant impact on the overall rating.
Never-Verified Reviewers
253 of the 609 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 9.6 while the reviewers who have written at least one verified purchase review 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.
Take-Back Reviewers
195 of the 609 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 9.7 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.
Single-Day Reviewers
139 of the 609 reviewers have written multiple reviews but posted all of them on a single day. The Single-Day reviewers have rated this product an average of 9.4 while all other reviewers rated this product an average of 9.1. 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.
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 9.2, 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.
49 of the 609 total reviews for this product use substantial repetitive phrases between them. These reviewers have rated this product an average of 9.6 while reviews without substantial repetitive phrases rated this product an average of 9.1. 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.
Warn Rating Trend
-
- 7%
- Created over 7 days
We counted 609 reviews for this product over the span of 743 days, an average of 0.8 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 5 or fewer reviews on any given day.
However, we see the following 7 days exceeding this threshold:In total, we found that 45 reviews were created on just 7 days. Although any days with a larger number of reviews than expected is suspicious, these reviews do not appear to have a significant impact on the overall rating.
Warn Reviewer Participation
-
- 82%
- 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 497 reviewers (or 82%) are within an overrepresented participation group.
