Analysis Details
Fail Rating Trend
-
- 35%
- Created over 108 days
We counted 3,815 reviews for this product over the span of 2,070 days, an average of 1.8 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 8 or fewer reviews on any given day.
However, we see the following 108 days exceeding this threshold:In total, we found that 1,344 reviews were created on just 108 days. The reviews on these high volume days have rated this product an average of 3.4 while reviews from other days have rated this product an average of 3.2. 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.
Fail Suspicious Reviewers

The One-Hit Wonders have rated this product an average of 2.4 while the reviewers who have posted more than one review have rated this product an average of 3.3.

The Single-Day reviewers have rated this product an average of 3.8 while all other reviewers rated this product an average of 3.3.

Warn Deleted Reviews
We discovered a total of 85 deleted Reviews for this product, with an average rating of 4.2. 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.
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.
Warn Reviewer Participation
-
- 69%
- From reviewers with an overrepresented participation
We see the following 3 participation groups with a statistically significant greater concentration than what we'd expect to see:In total, we found that 2636 reviewers (or 69%) are within an overrepresented participation group. This is an excessively high number of reviewers in overrepresented participation groups.
