Analysis Details

Note: While Amazon claims 2,908 reviews, we counted 2,907 available on their site.

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.


1 of the 2,907 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 1.0 while reviews that were not incentivized rated this product an average of 4.7. 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


395 of the 2,907 reviewers have only reviewed this product. While this is more One-Hit Wonders than we'd expect to see, it does not appear to have a significant impact on the overall rating.

Never-Verified Reviewers


68 of the 2,907 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 4.7. 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.

Take-Back Reviewers


1,036 of the 2,907 reviewers have had at least one of their past reviews for another product deleted. This is an excessively large percentage of Take-Back Reviewers which may indicate unnatural reviews.

Fail Reviewer Ease
The ease score is the average rating for all reviews that a given reviewer submits. The average ease score for reviewers of this product is 4.4, while the average ease score for reviewers in this category is 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 Word Count Comparison

  • 34%
  • Have an overrepresented word count

In the graph above, we can see the distribution of review word counts for this product and the expected distribution for this category. We see the following 1 group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 990 reviews (or 34%) are within an overrepresented word count group. These reviews have rated this product an average of 4.9, while all other reviews 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 Overlapping Review History
Does not include products
from the same brand


320 of the 2,907 reviewers have substantial overlapping product review history. These reviewers have rated this product an average of 4.8 while the reviewers who have a more unique product review history 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
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 -5.0 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.

Warn Deleted Reviews

We discovered a total of 15 deleted reviews for this product, with an average rating of 4.1. Even though deleted reviews don't affect the average rating, the fact that action was taken to delete reviews raises some red flags about the integrity of the reviews for the product as whole.

Warn Reviewer Participation

  • 50%
  • From reviewers with an overrepresented participation

We see the following 1 participation group with a statistically significant greater concentration than what we'd expect to see:In total, we found that 1441 reviewers (or 50%) are within an overrepresented participation group. While this is more reviews from overrepresented participation groups than we'd expect to see, these reviews do not appear to have a significant impact on the overall rating.

Pass Rating Trend

We counted 2,907 reviews for this product over the span of 1,217 days, an average of 2.4 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 9 or fewer reviews on any given day.

However, we see the following 5 days exceeding this threshold:In total, we found that 56 reviews were created on just 5 days. This is within an acceptable range and it does not appear to be significantly affecting the overall rating for this product.
