How We Score Products at ChuanFly

At ChuanFly, we take product reviews seriously. Our scoring methodology is designed to be transparent, consistent, and helpful for making informed purchasing decisions. Every product we review goes through the same rigorous evaluation process.

Our Scoring Criteria

Each product is evaluated across 5 key dimensions, each weighted by importance:

• Performance (30%) — How well does the product do what it promises? We run standardized tests to measure speed, accuracy, durability, and output quality.
• Value for Money (25%) — Does the price match the quality? We compare features and performance against similarly priced alternatives to determine if you’re getting a fair deal.
• Build Quality & Design (20%) — We assess materials, construction, ergonomics, and aesthetic appeal. A well-built product should last.
• Ease of Use (15%) — Can anyone pick it up and use it? We evaluate setup difficulty, learning curve, documentation quality, and day-to-day usability.
• Support & Warranty (10%) — What happens if something breaks? We check warranty terms, customer support responsiveness, and return policies.

How We Test

Our testing process follows these steps:

1. Research Phase — We identify market-leading products based on sales data, brand reputation, and community feedback.
2. Purchase Phase — We buy products at retail price through standard channels. We do not accept free samples for review to avoid bias.
3. Testing Phase — Each product undergoes 20+ hours of hands-on testing across our 5 criteria. Tests are performed in real-world conditions, not labs.
4. Comparison Phase — Products are tested side-by-side against direct competitors in the same price bracket.
5. Scoring Phase — Scores are calculated using our weighted formula. Team members vote independently to prevent individual bias.
6. Review Phase — Scores are reviewed for consistency. If a product scores significantly above or below expectations, we re-test.

Score Interpretation

• 9.0 – 10.0 — Outstanding. Best in class. Highly recommended.
• 8.0 – 8.9 — Excellent. Performs well above average. Worth considering.
• 7.0 – 7.9 — Good. Solid performance with minor drawbacks.
• 6.0 – 6.9 — Average. Does the job but nothing special.
• Below 6.0 — Below expectations. Significant issues found.
