Analysis Details
Fail Deleted Reviews
We discovered a total of 357 deleted Reviews for this product, with an average rating of 4.8. 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
-
- 17%
- Created over 20 days
We counted 538 reviews for this product over the span of 1,627 days, an average of 0.3 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 3 or fewer reviews on any given day.
However, we see the following 20 days exceeding this threshold:In total, we found that 90 reviews were created on just 20 days. This is an excessively high number of reviews submitted on these high volume days.
Warn Suspicious Reviewers
Take-Back Reviewers
252 of the 538 reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, it does not appear to have a significant impact on the overall rating.

- Have an overrepresented word count
