Review Analysis Results
Analysis Summary
The overwhelming majority of these reviews appear genuine, with only 2 out of 15 reviews showing clear manipulation patterns. Most reviews (approximately 87%) demonstrate authentic user experiences with specific personal details, medical contexts, and balanced perspectives that would be difficult to fabricate consistently. The high verification rate (all marked 'V') further supports authenticity, as verified purchases are less likely to be fake.
Strong evidence of authenticity includes detailed personal medical histories (review 4 mentions being a physician with specific tendinitis issues since September 2021), multi-year usage reports (review 1 references four years of use), balanced critiques (review 5 discusses battery issues while still rating the product), and specific therapeutic applications (review 9 mentions using it on a dog's neck injury). Many reviews include nuanced experiences like 'it's a little heavier than it looks' or 'swelling has been largely reduced' rather than generic praise.
The primary concerns are limited to two reviews: review 13 uses marketing language ('FDA approved medical 2 device is a clinical therapeutic device') and appears to be written from a promotional perspective, while review 14 contains unusual phrasing ('I can feel it healing me and I even crave it when I'm not using it') that reads as exaggerated. These represent clear outliers in an otherwise authentic review set.
Overall, this product appears to have genuinely satisfied users who provide detailed, specific feedback about pain relief for various conditions. The few suspicious reviews don't undermine the clear pattern of authentic experiences from verified purchasers. The low fake percentage reflects that most reviews contain the personal context and specific details characteristic of real users rather than coordinated manipulation.
Key patterns identified in the review analysis include: Multi-year usage reports, Specific medical conditions mentioned, Balanced critiques alongside praise.

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 (4.10 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 (4.40 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.
