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 first impression

Packaging and contents

Here we take a closer look at the packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The Letterman 6 from Radius makes a solid impression as soon as it is unpacked. It is delivered in a very sturdy cardboard box, which protects the product sufficiently from possible damage. However, the sustainability of the packaging has to be rated negatively due to the additional use of plastic film. The contents of the packaging are complete and include the letterbox, four spacers and a practical LED sensor light. The operating instructions are available in German and English. It is noticeable that all words, including the beginnings of sentences and nouns, are written in lower case, which seems a little unusual but does not impair comprehensibility.
