Analysis Details


Fail Deleted Reviews

Fail Suspicious Reviewers

One-Hit Wonders


9 of the 139 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 2.3 while the reviewers who have posted more than one review have rated this product an average of 3.8. 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.
