Fail Suspicious Reviewers

One-Hit Wonders


147 of the 362 reviewers have only reviewed this product. This is an excessively large percentage of One-Hit Wonders which may indicate unnatural reviews.

Never-Verified Reviewers


127 of the 362 reviewers have never written a verified purchase review. While this is more Never-Verified Reviewers than we'd expect to see, it does not appear to have a significant impact on the overall rating.

Take-Back Reviewers


55 of the 362 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.

Single-Day Reviewers


70 of the 362 reviewers have written multiple reviews but posted all of them on a single day. While this is more Single-Day Reviewers than we'd expect to see, the discrepancy in ratings between the Single-Day Reviewers and all other reviewers isn't significant enough to rule out the possibility of it being due to random chance.

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 9.2, while the average ease score for reviewers in this category is 8.8. 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.

113 of the 362 reviewers have substantial overlapping product review history. These reviewers have rated this product an average of 9.7 while the reviewers who have a more unique product review history rated this product an average of 9.3. 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 -4.9 while the positive reviews had an average net helpfulness score of 0.5. 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 5 deleted reviews for this product, with an average rating of 9.6. 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.

Pass Rating Trend

  • Created over 3 days

We counted 362 reviews for this product over the span of 1,161 days, an average of 0.3 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 3 or fewer reviews on any given day.

However, we see the following 3 days exceeding this threshold:In total, we found that 12 reviews were created on just 3 days. This is within an acceptable range and it does not appear to be significantly affecting the overall rating for this product.
