Stiftung warehouse is an independent goods and service evaluation institution established by the German Bundestag in december1964. Its tests and surveys cover almost all areas of our daily lives. The test samples are not provided by the manufacturer, but purchased anonymously in the store to avoid the impact of contact with the manufacturer on its reputation.
96% of Germans know about Stiftung warehouse, and one third of Germans will refer to the inspection report of the agency to decide on the product selection when purchasing important goods.
