When buying a new home appliance, you want to be certain that you've made the right choice. So it's good that there are independent comparative tests. Alongside satisfied customers, they are the best proof that we keep our quality promise.
Stiftung Warentest is a German consumer organisation and foundation involved in investigating and comparing goods and services in an unbiased way. Stiftung Warentest carries out more than 200 comparative product tests and investigations of services from nearly all areas of everyday life every year.
The investigations are not actually carried out by Stiftung Warentest's staff members themselves, but by independent external test institutes worldwide. Test samples are purchased anonymously in shops and not provided by the manufacturers.
The classification of the evaluation results is based on the marking system used in German schools. This results in the following categories for the overall verdicts on the quality of goods and services:
0.5 – 1.5: "very good"
1.6 – 2.5: "good"
2.6 – 3.5: "satisfactory"
3.6 – 4.5: "adequate"
4.6 – 5.5: "unsatisfactory"
