How do we test?
As part of the product test, we test products under real everyday conditions. Precise measurement variables are combined with systematically recorded user observations. This provides authentic, reliable results instead of sterile laboratory data — a reliable basis for transparent recommendations and safe purchasing decisions.

Product and
Service certification
The DTI checks product and service quality separately and awards two independent, legally certified seals in return. A standardized questionnaire ensures objective comparability, makes the tested quality transparently comprehensible and demonstrably strengthens the trust of your customers.
Place the DTI seal prominently in shops, advertising and on packaging. Consumers immediately recognize proven quality — this increases click and purchase rates.
Independently verified quality reduces purchase doubts. Experience has shown that shops with the DTI seal achieve significantly higher closing rates.
More conversions mean lower costs per sale and higher ROI. At the same time, the seal improves your customer lifetime value in the long term.
Two seals, double effect
With the dual DTI seals for product and service quality, you also prove the certified quality of your product and service processes. This double award makes excellence visible at a glance and demonstrably strengthens the trust of your customers.
Verified quality
Our certification has been proven to result in a significant increase in sales. Use the trust that our seal creates with your customers to drive up your sales figures.
A standardized questionnaire examines your product in seven clearly defined quality categories and provides objective, independent results that consumers can rely on.
