Data Sourcing & Anti-Spam Damping
How the User Score & Sentiment is Evaluated
Rather than relying on unverified comment sections, we aggregate customer feedback exclusively from verified purchasers across leading international retail platforms (such as Amazon, Bol, MediaMarkt, and Otto).
80% Rating Quality: The normalized consensus rating awarded by verified buyers across multiple international markets.
20% Popularity Volume & Statistical Significance: Mapped through a logarithmic decay function (Top 8% Cap). This ensures statistically significant samples while preventing cheap mass-market items with 40,000+ incentivized reviews from crowding out superior low-volume engineering.
We routinely filter out promotional reviews, incentivized submissions, and counterfeit seller feedback. User scores are updated on a rolling basis to reflect long-term durability.
