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.

Amaazu
Letterbox

The letterbox from Amaazu is an elegant and functional solution for the front door. With two different designs, it offers individual design options, while the modern, linear design in an elegant matt finish and with a polished stainless steel cover is a highlight. The horizontal viewing window and concealed lock ensure an aesthetically pleasing appearance. High-quality materials such as V2A quality steel make the letterbox weather-resistant and durable. In the test, the simple one-handed operation and the easy-to-read nameplate were impressive. The only negative aspect was that no information was provided on sustainability. The Amaazu letterbox combines design, functionality and quality to create an attractive and practical solution at the front door.

Advantages

✅ Two different designs
✅ Simple installation
✅ Durable quality
✅ Easy cleaning and care

Disadvantages

❌ Lack of information on sustainability

The first impression

Packaging and contents

ℹ️ 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?

Weighting: 20%
*The maximum score is 100 points

The letterbox from Amaazu impresses as soon as it is unpacked with its well thought-out packaging, which is perfectly matched to the size of the product. The product protection is exemplary, as the letterbox is delivered without scratches or soiling. A positive aspect in terms of sustainability is the deliberate avoidance of unnecessary packaging waste through the sensible use of plastic film. The contents of the packaging are extensive and include not only the letterbox with newspaper tube, but also two keys and all installation utensils. The enclosed installation instructions are largely self-explanatory, but the clearly written instructions make it easy to install the product.

Our practical test of the Amaazu letterbox has shown that the manufacturer impressively lives up to its advertising promises. The product’s weather resistance thanks to the use of V2A stainless steel proved to be extremely reliable, which supports long-term outdoor use. The easy cleaning of the letterbox facilitates maintenance and contributes to lasting cleanliness. The interchangeability of the nameplates is uncomplicated and enables individual design. The precise workmanship of the viewing window makes it easy to see incoming mail. The letterbox is also easy to install and attach, which makes installation easier for the end user and contributes to a positive overall experience.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good performance in the mid-price segment80 points
Rating cut4.2 out of 5.0 on Amazon60 points

Weighting: 15%
*The maximum score is 100 points

The letterbox from Amaazu has 4.2 out of 5.0 stars on Amazon.
One common complaint is that the letterbox is prone to scratches and scratches from light pressure. Many customers like the stability and durability of the letterbox, which is characterized by robust material and an overlapping flap with effective protection for the lock and insertion. The practical drainage holes in case of water ingress are also appreciated by customers. Some reviewers positively emphasize the quick assembly, the sturdy workmanship and the appealing appearance of the product. In our own practical test, we were able to confirm the positive aspects, particularly with regard to weather resistance and ease of cleaning.

Prices of up to € 160 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €25. The Amaazu letterbox is therefore currently in the middle price segment with a price of €75.95. For the quality and performance received, the price-performance ratio is good.
