The unverified purchasers have rated this product an average of 3.4 while the verified purchasers 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.

  • Created over 110 days

We counted 11,638 reviews for this product over the span of 2,417 days, an average of 4.8 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 110 days exceeding this threshold:In total, we found that 1,889 reviews were created on just 110 days. This is an excessively high number of reviews submitted on these high volume days.
