Analysis Details

Note: While Amazon claims 20,622 reviews, we counted 20,127 available on their site.

Fail Rating Trend

  • 45%
  • Created over 26 days

We counted 20,127 reviews for this product over the span of 275 days, an average of 73.2 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 103 or fewer reviews on any given day.

However, we see the following 26 days exceeding this threshold:In total, we found that 8,965 reviews were created on just 26 days. The reviews on these high volume days have rated this product an average of 4.4 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.
