Review Analysis Results
Analysis Summary
The overwhelming majority of these reviews appear genuine, with only minimal indications of potential manipulation. All 16 reviews are verified purchases (marked with 'V'), which significantly increases their credibility. The reviews display a natural distribution of ratings (mostly 5-star with some 4-star and one 3-star), and contain specific personal experiences that would be difficult to fabricate consistently. The genuine signals far outweigh any concerns, suggesting this is a legitimate product receiving mostly positive feedback from real users.
Strong evidence of authenticity includes numerous reviews with specific personal context and detailed usage scenarios. Review #1 describes using the device 'out of curiosity' and mentions its lightweight design and ease of use for beginners. Review #3 provides specific testing locations (phone, TV, microwave, router) and includes a safety warning. Review #10 is written in Italian with specific testing on PS4, oven, and cell phone, mentioning a brief calibration period. Review #12 is in Spanish discussing paranormal investigation beginners. These varied, specific experiences across different languages strongly indicate genuine users.
The only minor concerns are a few extremely brief reviews (#5, #6, #11) that lack detail, but these could simply represent satisfied customers who don't elaborate. Review #5 ('Just as pictured, arrived fast, works great') follows a common pattern but includes shipping feedback. Review #6 ('Works well!') is extremely brief but not necessarily fake. No reviews show clear marketing language, repetitive phrases across multiple reviews, or other definitive manipulation patterns. The one 3-star review (#7) provides balanced criticism about the lack of sound alerts, which adds credibility to the overall review set.
Overall, this appears to be a legitimate product receiving mostly positive feedback from verified purchasers. The reviews show natural variation in length, detail, and language, with specific personal experiences that would be difficult to coordinate in a manipulation campaign. While a few reviews are brief, they don't display the clear patterns associated with fake reviews. The product seems to work as advertised for detecting EMF from common household electronics, with some users applying it to paranormal investigation.
Key patterns identified in the review analysis include: Verified purchases only, Specific device testing mentioned (microwave, router, phone), Mixed language reviews (English, Italian, Spanish).

Understanding This Analysis
What does Grade B mean?
This product has good review authenticity with minor concerns. While most reviews appear genuine, we detected some patterns that warrant mild caution.
Adjusted Rating Explained
The adjusted rating (4.40 stars) represents what we estimate this product's rating would be if fake reviews were removed. This product's adjusted rating is lower than Amazon's displayed rating (4.67 stars), suggesting positive fake reviews may be inflating the score.
How We Detect Fake Reviews
Our AI analyzes multiple factors: language patterns (generic vs. specific), reviewer behavior (history, timing), temporal anomalies (review clusters), verification status, sentiment authenticity, and statistical outliers. No single factor determines a review is fake - we look at the combination of signals.
Important Limitations
No automated system is perfect. Sophisticated fake reviews can evade detection, and some genuine reviews may be incorrectly flagged. Use this analysis as one data point in your purchasing decision, not the only factor. Reading actual review content yourself is always valuable.
