Штифтунг Варентест
Stiftung Warentest carries out more than 200 comparative product tests and investigations of services from nearly all areas of everyday life every year. Since 2002, products and services on special limited offer, mainly by the discount retailer chains, have also been investigated every week and the results quickly published. Aspects of corporate social responsibility (CSR) have been a part of the investigations of some specified products since 2004. There is also a section on investigated medication ("Medikamente im Test"), which provides information about more than 9000 medicines and 175 areas of application.
