Analysis Details
Fail Suspicious Reviewers
One-Hit Wonders
10 of the 60 reviewers have only reviewed this product. The One-Hit Wonders have rated this product an average of 3.5 while the reviewers who have posted more than one review 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.
Warn Rating Trend
-
- 10%
- Created over 3 days
We counted 60 reviews for this product over the span of 3,046 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 1 or fewer reviews on any given day.
However, we see the following 3 days exceeding this threshold:In total, we found that 6 reviews were created on just 3 days. Although any days with a larger number of reviews than expected is suspicious, the discrepancy in ratings from reviews created on these high volume days and reviews created on other days isn't significant enough to rule out the possibility of it being due to random chance.
Warn Reviewer Participation
-

- From reviewers with an overrepresented participation

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.
