Fail Deleted Reviews
We discovered a total of 4 deleted Reviews for this product, with an average rating of 4.8. 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.
Fail Unverified Purchases
6 of the 73 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 3.8 while the verified purchasers 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.
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
Never-Verified Reviewers
1 of the 73 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 1.0 while the reviewers who have written at least one verified purchase review 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.
Take-Back Reviewers
57 of the 73 reviewers have had at least one of their past reviews for another product deleted. This is an excessively large percentage of Take-Back Reviewers which may indicate unnatural reviews.

- 18%
- Created over 3 days
We counted 73 reviews for this product over the span of 224 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 13 reviews were created on just 3 days. This is an excessively high number of reviews submitted on these high volume days.

40 of the 73 reviewers have substantial overlapping product review history. While this is more than we'd expect to see, the discrepancy in ratings between these reviewers and reviewers who have a more unique product review history isn't significant enough to rule out the possibility of it being due to random chance.
