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 maximum score is 100 points

Our practical test has shown that the manufacturer of K Kaffeereiniger24 keeps its promises. The dosage of the cleaning tablets is optimal, as they are already pre-dosed and therefore sufficient for 200 applications. This makes them easy to use and saves time when preparing for cleaning. In addition, we were unable to detect any changes in odor or taste, which indicates that the tablets are odorless and tasteless.

When using the cleaning tablets, follow the instructions of the coffee machine manufacturer . In our test, we tested both a machine in which the tablet is dissolved beforehand and a machine in which the tablet is inserted directly. In both cases, the tablet dissolved very quickly , so that quick and efficient cleaning was possible.

The cleaning result was very good in our test. No residues were detected, meaning that the fully automatic coffee machine was cleaned perfectly . This confirms the excellent cleaning power of K Kaffeereiniger24 cleaning tablets.

Overall, we can confirm that the manufacturer keeps its advertising promises. Dosage, odor and taste neutrality, application and cleaning results correspond to the manufacturer’s specifications and offer an effective solution for cleaning fully automatic coffee machines.

On the Amazon platform, consumers rate the product with an average of 4.6 stars. Positive customer reviews emphasize that they are satisfied with the product and that it is well packaged. Some customers state that they would buy the product again. The cleaning result is also rated as very good. However, there are also negative customer reviews of the product.
