Analysis Details
Fail Deleted Reviews
We discovered a total of 7 deleted Reviews for this product, with an average rating of 5. 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.
Fail Brand Repeats
Brand Repeaters
62 of the 121 reviewers have reviewed other products for this brand. While this is more Brand Repeaters than we'd expect to see, the discrepancy in ratings between the Brand Repeaters and non-repeaters isn't significant enough to rule out the possibility of it being due to random chance.
Brand Loyalists
12 of the 121 reviewers have reviewed multiple products but half or more of their reviews are for this brand. This is an excessively large percentage of Brand Loyalists which may indicate unnatural reviews.
Fail Suspicious Reviewers
Take-Back Reviewers
86 of the 121 reviewers have had at least one of their past reviews for another product deleted. This is an excessively large percentage of Take-Back Reviewers which may indicate unnatural reviews.
Fail 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 4.8, while the average ease score for reviewers in this category is 4.4. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.

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.
63 of the 121 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.
Read more about our Incentivized Reviews test. Check out our study showing that Incentivized Reviewers are much more likely to leave a positive review.
Warn Phrase Repetition
Reviews that contain one of these phrases are NOT necessarily devalued; read more about how this test works here.
71 of the 121 total reviews for this product use substantial repetitive phrases between them. This is an excessively large percentage which may indicate unnatural reviews.

Radha Beauty Essential Oil Diffuser for... by Radha Beauty
61 of the 121 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.
