Most Trusted ReviewsWe couldn't find any quality reviews
6 of the 21 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 4.7 while the reviewers who have posted more than one review have rated this product an average of 3.0. 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.
9 of the 21 reviewers have never written a verified purchase review. While this is more Never-Verified Reviewers than we'd expect to see, the discrepancy in ratings between the Never-Verified Reviewers and reviewers who have written at least one verified purchase review isn't significant enough to rule out the possibility of it being due to random chance.
5 of the 21 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 2.2 while all other reviewers rated this product an average of 3.9. 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.
- Created over 1 day
We counted 21 reviews for this product over the span of 65 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 1 day exceeding this threshold:
- Unverified Purchases
21 of the 21 total reviews for this product are unverified purchases. This is an excessively large percentage of unverified purchases and it may indicate 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.
- 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:
