Analysis Details
Fail Rating Trend
-
- 94%
- Created over 2 days
We counted 234 reviews for this product over the span of 37 days, an average of 6.3 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 16 or fewer reviews on any given day.
However, we see the following 2 days exceeding this threshold:In total, we found that 221 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 1.6. 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.
Fail Unverified Purchases
221 of the 234 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 1.6. 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 Suspicious Reviewers
One-Hit Wonders
8 of the 234 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 3.4 while the reviewers who have posted more than one review have rated this product an average of 4.9. 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.
Never-Verified Reviewers
218 of the 234 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 2.3. 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
3 of the 234 reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, the discrepancy in ratings between the Take-Back Reviewers and reviewers who don't have any deleted reviews in their history isn't significant enough to rule out the possibility of it being due to random chance.
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 4.8, while the average ease score for reviewers in this category is 4.3. 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.

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.
