Analysis Details
Warn Rating Trend
-
- 7%
- Created over 17 days
We counted 994 reviews for this product over the span of 2,934 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 17 days exceeding this threshold:In total, we found that 72 reviews were created on just 17 days. Although any days with a larger number of reviews than expected is suspicious, these reviews do not appear to have a significant impact on the overall rating.

The average ease score for reviewers of this product is 4.4, while the average ease score for reviewers in this category is 4.2.

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.
