For Consumers
The Prüfengel Institute tests products and services and publishes the results in free publications on the Internet.
As an independent and private institute, we are free to plan the test. We not only test selected products, but every manufacturer gets the chance to make their products available for testing.
Our experts
Our product testers are specialized and trained in individual product categories. The categories are broken down into sports & leisure, cars & motorcycles, hardware stores, household, technology, etc. The products to be tested are assigned to the respective experts. This allows every employee to carry out the certifications as effectively as possible.
The products are tested in a test catalog specially developed by us. You will receive more information about our test procedure here.
