Warn Incentivized Reviews
On Oct 3, 2016, Amazon prohibited incentivized reviews, however we still test for them since there are still millions in our dataset.


3 of the 7 total reviews for this product admitted to receiving a free or discounted product in exchange for a review. This is an excessively large percentage of incentivized reviews which may indicate unnatural reviews.

Warn Reviewer Ease
The ease score is the average rating for all reviews that a given reviewer submits. The average ease score for reviewers of this product is 4.7, while the average ease score for reviewers in this category is 4.3. While this discrepancy is rather large, it is not quite large enough to rule out the possibility of it being due random chance.

Common Phrases in Reviews:
2 reviews


2 of the 7 total reviews for this product use substantial repetitive phrases between them. While this is more than we'd expect to see, it does not appear to have a significant impact on the overall rating.

Warn Overlapping Review History
Reviewers of this product have ALSO reviewed the following products:

Does not include products
from the same brand


5 of the 7 reviewers have substantial overlapping product review history. While this is more than we'd expect to see, the discrepancy in ratings between these reviewers and reviewers who have a more unique product review history isn't significant enough to rule out the possibility of it being due to random chance.
