Analysis Details
Fail Deleted Reviews
We discovered a total of 180 deleted Reviews for this product, with an average rating of 5. 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.
Fail Rating Trend
-
- 100%
- Created over 3 days
We counted 1,355 reviews for this product over the span of 18 days, an average of 75.3 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 105 or fewer reviews on any given day.
However, we see the following 3 days exceeding this threshold:In total, we found that 1,353 reviews were created on just 3 days. The reviews on these high volume days have rated this product an average of 5.0 while reviews from other days have rated this product an average of 1.0. 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
Never-Verified Reviewers
1,033 of the 1,355 reviewers have never written a verified purchase review. This is an excessively large percentage of Never-Verified Reviewers which may indicate unnatural reviews.
Take-Back Reviewers
257 of the 1,355 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
882 of the 1,355 reviewers have written multiple reviews but posted all of them on a single day. This is an excessively large percentage of Single-Day Reviewers which may indicate unnatural reviews.
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 4.9, while the average ease score for reviewers in this category is 4.1. 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 Reviewer Participation
