How are Trustami star ratings calculated, and are they trustworthy?
How Trustami works
To provide you with a comprehensive and honest picture of our customer satisfaction, we use the independent Trustami review system.
Unlike conventional systems, Trustami does not collect feedback in just one place; instead, it aggregates all verified customer reviews from across our sales channels, marketplaces, and portals (e.g., Amazon, Google, industry-specific sites, facebook).
Here is the Trustami profile for Functional Cosmetics Company AG.
Here is how the overall rating is calculated:
- Aggregated total: Trustami continuously captures all genuine buyer reviews from the connected profiles.
- Mathematical average: An intelligent algorithm calculates the overall average on a scale of 1 to 5 stars in real-time, based on the proportion of positive, neutral, and negative feedback.
- Transparent overall result: The displayed stars therefore reflect the entirety of our customer experiences—not just a small subset.
Is Trustami trustworthy?
Yes, absolutely. Trustami was developed as a spin-off from the Technical University of Berlin and is a German service provider that operates according to strict standards.
The system is particularly tamper-proof and reliable for the following reasons:
- Authenticity check & verification: Only reviews based on genuine transactions and verified customer profiles from the respective platforms are included.
- No selective filtering: As a merchant, we have no influence over which individual reviews are evaluated. Trustami synchronizes and updates the data automatically.
- Manipulation or deletion of negative reviews is not possible.Compliance with European regulations (EU Omnibus Directive): Trustami meets the EU's strict transparency requirements regarding information on the authenticity of consumer reviews.
- Independent verification: Simply click on the Trustami seal in the shop – this takes you directly to the public Trustami certificate, where you can view details of all connected sources and individual reviews.
