Analysis Details
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 Phrase Repetition
Reviews that contain one of these phrases are NOT necessarily devalued; read more about how this test works here.
1,298 of the 19,151 total reviews for this product use substantial repetitive phrases between them. These reviewers have rated this product an average of 4.9 while reviews without substantial repetitive phrases 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 Reviewer Participation
-
- 67%
- From reviewers with an overrepresented participation
We see the following 2 participation groups with a statistically significant greater concentration than what we'd expect to see:In total, we found that 12826 reviewers (or 67%) are within an overrepresented participation group. These reviews have rated this product an average of 4.7, 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.
Warn Deleted Reviews
We discovered a total of 166 deleted Reviews for this product, with an average rating of 4.6. 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.
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 Rating Trend
-
- 67%
- Created over 298 days
We counted 19,151 reviews for this product over the span of 2,067 days, an average of 9.3 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 21 or fewer reviews on any given day.
However, we see the following 298 days exceeding this threshold:In total, we found that 12,824 reviews were created on just 298 days. This is an excessively high number of reviews submitted on these high volume days.

Take-Back Reviewers
