Analysis Details


Fail Deleted Reviews

Fail Suspicious Reviewers

One-Hit Wonders


2,527 of the 10,952 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 2.5 while the reviewers who have posted more than one review have rated this product an average of 3.5. 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

  • 11%
  • Created over 68 days

We counted 10,952 reviews for this product over the span of 2,102 days, an average of 5.2 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 14 or fewer reviews on any given day.

However, we see the following 68 days exceeding this threshold:In total, we found that 1,221 reviews were created on just 68 days. Although any days with a larger number of reviews than expected is suspicious, the discrepancy in ratings from reviews created on these high volume days and reviews created on other days isn't significant enough to rule out the possibility of it being due to random chance.
