About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

The individual setting of the storage or minimum shelf life date ensures long-lasting freshness and the airtight vacuum seal preserves the aroma. The product also guarantees clean and hygienic storage of the coffee. The simple closure makes it easy to use in everyday life, while the innovative one-way valve seals the coffee container. The generous capacity (1900 ml) corresponds to standard coffee packs and allows the coffee to be left directly in the can. The dosing spoon supplied enables exact portioning for perfect preparation. The choice of three different sizes (900 ml, 1300 ml and 1900 ml) or a set of all three sizes offers the customer flexibility. All in all, the Coffee Fox® vacuum coffee can is an excellent choice for coffee lovers who value freshness combined with practical handling.
