Analysis Details
Fail Deleted Reviews
We discovered a total of 3 deleted Reviews for this product, with an average rating of 1. 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.

- Created over 2 days
We counted 16 reviews for this product over the span of 845 days, an average of 0.0 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 1 or fewer reviews on any given day.
However, we see the following 2 days exceeding this threshold:In total, we found that 4 reviews were created on just 2 days. This is an excessively high number of reviews submitted on these high volume days.
Warn Unverified Purchases
11 of the 16 total reviews for this product are unverified purchases. While this is a higher percentage of unverified purchases than we'd expect to see, it does not appear to have a significant impact on the overall rating.
