Analysis Details
Fail Unverified Purchases
374 of the 2,839 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 2.5 while the verified purchasers have rated this product an average of 3.3. 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.
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
99 of a random sample of 2,838 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 2.4 while the reviewers who have posted more than one review have rated this product an average of 3.2. 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
78 of a random sample of 2,838 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 2.3 while the reviewers who have written at least one verified purchase review rated this product an average of 3.2. 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
954 of a random sample of 2,838 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, it does not appear to have a significant impact on the overall rating.
Fail Phrase Repetition
Reviews that contain one of these phrases are NOT necessarily devalued; read more about how this test works here.
Common Phrases in Reviews:
76 reviews
(3.2/5)

(3.7/5)
26 of the 2,839 total reviews for this product use substantial repetitive phrases between them. These reviewers have rated this product an average of 3.9 while reviews without substantial repetitive phrases rated this product an average of 3.2. 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 10 deleted Reviews for this product, with an average rating of 2. 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
-
- 65%
- Created over 71 days
We counted 2,839 reviews for this product over the span of 1,402 days, an average of 2.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 8 or fewer reviews on any given day.
However, we see the following 71 days exceeding this threshold:In total, we found that 1,838 reviews were created on just 71 days. This is an excessively high number of reviews submitted on these high volume days.
Warn Reviewer Participation
-
- 57%
- From reviewers with an overrepresented participation
We see the following 2 participation groups with a statistically significant greater concentration than what we'd expect to see:In total, we found that 1612 reviewers (or 57%) are within an overrepresented participation group. This is an excessively high number of reviewers in overrepresented participation groups.
