Analysis Details

Fail Suspicious Reviewers

One-Hit Wonders


2,117 of a random sample of 19,259 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 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.

Take-Back Reviewers


5,779 of a random sample of 19,259 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.

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 41 deleted reviews for this product, with an average rating of 3.5. 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:
  1. 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.
  2. We have no information on reviews that were never published in the first place.
  3. 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

  • 62%
  • Created over 201 days

We counted 19,427 reviews for this product over the span of 2,095 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 201 days exceeding this threshold:In total, we found that 11,952 reviews were created on just 201 days. This is an excessively high number of reviews submitted on these high volume days.
