The unverified purchasers have rated this product an average of 4.9 while the verified purchasers have rated this product an average of 4.3.

Incentivized reviews have rated this product an average of 4.9 while reviews that were not incentivized rated this product an average of 4.5.

Warn Rating Trend

  • 8%
  • Created over 2 days

We counted 180 reviews for this product over the span of 183 days, an average of 1.0 review per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 5 or fewer reviews on any given day.

However, we see the following 2 days exceeding this threshold:In total, we found that 15 reviews were created on just 2 days. Although any days with a larger number of reviews than expected is suspicious, the discrepancy in ratings from reviews created on these high volume days and reviews created on other days isn't significant enough to rule out the possibility of it being due to random chance.

Pass Deleted Reviews
  • 0
  • Reviews have been deleted
We have not discovered any deleted reviews for this product.

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.
