- 29%
- Created over 9 days
We counted 152 reviews for this product over the span of 3,510 days, an average of 0.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 2 or fewer reviews on any given day.
However, we see the following 9 days exceeding this threshold:In total, we found that 44 reviews were created on just 9 days. The reviews on these high volume days have rated this product an average of 3.7 while reviews from other days have rated this product an average of 2.5. 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.
One-Hit Wonders
49 of the 152 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 4.2 while the reviewers who have posted more than one review have rated this product an average of 2.2. 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.

95 of the 152 reviewers have never written a verified purchase review. The Never-Verified Reviewers have rated this product an average of 3.1 while the reviewers who have written at least one verified purchase review rated this product an average of 2.4. 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
5 of the 152 reviewers have had at least one of their past reviews for another product deleted. The Take-Back Reviewers have rated this product an average of 1.4 while the reviewers who don't have any deleted reviews in their history have rated this product an average of 2.9. 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.

- Reviews have been deleted
There are a few limitations to keep in mind regarding the Deleted Reviews test:
- We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
- We have no information on reviews that were never published in the first place.
- We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.
