Analysis Details

Note: While Amazon claims 2,760 reviews, we counted 2,594 available on their site.

Fail Rating Trend

  • 12%
  • Created over 28 days

We counted 2,594 reviews for this product over the span of 1,677 days, an average of 1.5 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 7 or fewer reviews on any given day.

However, we see the following 28 days exceeding this threshold:In total, we found that 314 reviews were created on just 28 days. The reviews on these high volume days have rated this product an average of 4.5 while reviews from other days have rated this product an average of 4.3. 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 Incentivized Reviews
On Oct 3, 2016, Amazon prohibited incentivized reviews, however we still test for them since there are still millions in our dataset.


17 of the 2,594 total reviews for this product admitted to receiving a free or discounted product in exchange for a review. Incentivized reviews have rated this product an average of 4.8 while reviews that were not incentivized rated this product an average of 4.3. 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 Suspicious Reviewers

One-Hit Wonders


373 of the 2,594 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 4.5 while the reviewers who have posted more than one review have rated this product an average of 4.3. 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
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 -9.7 while the positive reviews had an average net helpfulness score of -13.6. 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.
