Review Analysis Results
Analysis Summary
The reviews show a very low percentage of fake content (12%). Analysis reveals: 1) High verification rate (32/40 reviews are verified purchases), 2) Natural rating distribution with both 5-star and 4-star reviews, 3) Authentic-sounding content with specific vehicle model details, installation experiences, and cost comparisons, 4) Minor grammatical variations and different writing styles suggesting genuine users, 5) Several reviews mention minor fitment issues or specific concerns, which is typical of authentic feedback. The few suspicious elements are outweighed by the overall authenticity indicators.

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 (1.20 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 (1.23 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.
