Analysis Details


Fail Deleted Reviews

We discovered a total of 14 deleted reviews for this product, with an average rating of 4.4. 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.

Fail Suspicious Reviewers

Take-Back Reviewers


Less than approximately 10% of reviewers have had at least one of their past reviews for another product deleted. The Take-Back Reviewers have rated this product an average of 3.0 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 4.1. 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.
