4 | Frequently Asked Questions
Do brands pay to appear in your lists?
No. We may earn a small commission if you purchase via Amazon links, but brands cannot buy placement or alter scores.
How often are rankings updated?
Data refresh is monthly; we re-test whenever a major hardware or firmware revision appears.
How accurate is the AI sentiment analysis?
Cross-checks show ±0.1 variance versus manual scoring on 500-review sample sets. Human editors still make the final call.
