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 disinfectant from Qindoo performed very well in our practical test.
Handling was consistently quick and easy, as the product is already mixed and can be used straight away. The user-friendliness was rated as very positive.
Another plus point was the minimal odor development, which dissipated after a short time and was hardly perceived as annoying. No residue was found on the instruments after drying. The cleaning effect was excellent, so that the treated instruments appeared visually and haptically flawless after the immersion bath.
Another decisive factor is safety. Despite the biocidal nature of the product, no hazard potential was identified if the instructions for use were observed. At no time during the entire test was there a health hazard for the user.
There are also no special requirements for the storage of the product; it can be stored at room temperature. The quality of the disinfectant did not change and its effectiveness was fully maintained.
Overall, the product can be recommended with a clear conscience due to its effectiveness, quality and safety .
