The Test Procedure

Our tests run according to a fixed and always the same process, so that an independent and objective evaluation of the products is possible. We test every product on site. This means that we not only collect information from the Internet, but also take a close look at the product and test it for certain characteristics. The final score is made up of a wide variety of categories such as packaging, design, quality and value for money.
