Analysis Details


Fail Rating Trend

  • 22%
  • Created over 6 days

We counted 325 reviews for this product over the span of 161 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 6 days exceeding this threshold:In total, we found that 72 reviews were created on just 6 days. The reviews on these high volume days have rated this product an average of 4.9 while reviews from other days have rated this product an average of 4.2. 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.

Fail Suspicious Reviewers

One-Hit Wonders

The One-Hit Wonders have rated this product an average of 3.2 while the reviewers who have posted more than one review have rated this product an average of 4.4.

Take-Back Reviewers


1 of the 325 reviewers has 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, the discrepancy in ratings between the Take-Back Reviewers and reviewers who don't have any deleted reviews in their history isn't significant enough to rule out the possibility of it being due to random chance.
