- Created over 29 days
We counted 15,714 reviews for this product over the span of 878 days, an average of 17.9 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 33 or fewer reviews on any given day.
However, we see the following 29 days exceeding this threshold:In total, we found that 1,179 reviews were created on just 29 days. The reviews on these high volume days have rated this product an average of 4.7 while reviews from other days have rated this product an average of 4.6. 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 Skewed Helpfulness
Skewed Helpfulness
We examined the average net helpfulness score of negative reviews against the average net helpfulness score of positive reviews. The net helpfulness score is the number of times a review has been marked as helpful minus the number of times a review has been marked as unhelpful. We found that the negative reviews had an average net helpfulness score of -0.4 while the positive reviews had an average net helpfulness score of -0.0. Based on our statistical modeling, this discrepancy is significant enough to believe that the difference is not due to random chance, but possibly due to influence of unnatural voting patterns.
