The Test Procedure

Our tests are carried out according to a fixed and always identical process, so that an independent and objective evaluation of the products is possible. We test every product on site. This means that we don’t just gather information from the Internet, but also take a close look at the product and test it for certain features. The final score is made up of various categories such as packaging, design, quality and value for money. The exact test catalog can be viewed here .
