The first impression

Packaging and contents

Here we take a closer look at 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 do not quite meet expectations: According to the information on the website, an LED sensor light should be included, but this is missing. 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.

The Letterman 6 from Radius delivers what it promises. The assembly instructions are easy to understand and make it easy to follow and carry out all the steps.

As far as protection against unauthorised access is concerned, the letterbox could not be opened in the test without the appropriate key, which offers a high level of security. The capacity is also very good and offers sufficient space for larger quantities of post and newspapers. Overall, the Letterman 6 impresses with its functionality, security and quality.
