Fail Deleted Reviews

Fail Suspicious Reviewers

Never-Verified Reviewers


44 of the 7,968 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 4.0 while the reviewers who have written at least one verified purchase review rated this product an average of 4.8. 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.

  • 8%
  • Created over 46 days

We counted 7,968 reviews for this product over the span of 2,621 days, an average of 3.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 10 or fewer reviews on any given day.

However, we see the following 46 days exceeding this threshold:In total, we found that 616 reviews were created on just 46 days. Although any days with a larger number of reviews than expected is suspicious, these reviews do not appear to have a significant impact on the overall rating.
