Fail Deleted Reviews
We discovered a total of 20 deleted reviews for this product, with an average rating of 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 Suspicious Reviewers
60 of the 395 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.
161 of the 395 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.
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 8.9, 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.

Warn Rating Trend
- Created over 21 days
We counted 395 reviews for this product over the span of 1,197 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 21 days exceeding this threshold:
Warn Unverified Purchases
252 of the 395 total reviews for this product are unverified purchases. While this is a higher percentage of unverified purchases than we'd expect to see, it does not appear to have a significant impact on the overall rating.
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.
Warn Sample Reviews
28 of the 395 total reviews for this product mentioned the word "sample" within their review. This is more than we would expect see; the presences of any reviews that mention the word "sample" indicates that there may be more, since not all reviewers will disclose that they used a sample within their review.
Warn Brand Repeats
9 of the 395 reviewers have reviewed multiple products but half or more of their reviews are for this brand. While this is more Brand Loyalists than we'd expect to see, the discrepancy in ratings between the Brand Loyalists and non-loyalists isn't significant enough to rule out the possibility of it being due to random chance.
Warn Word Count Comparison

Common Phrases in Reviews:
Show MoreShow Less

Warn Overlapping Review History
Reviewers of this product have ALSO reviewed the following products:
214 of the 395 reviewers have substantial overlapping product review history. While this is more than we'd expect to see, it does not appear to have a significant impact on the overall rating.
