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 sound of the Sonodrum Zungentrummel is clean, clear, soothing and harmonious. However, it should be noted that the volume can be perceived as somewhat loud , depending on the place of use and personal preference. It would be desirable to have soft mallets available to make the sound softer. The product can be played with the fingers (finger mallets) as well as with mallets . With the help of stickers on the reeds, simple melodies and complex tone sequences can be learned easily, making the instrument suitable for beginners of all ages. The sonodrum proves to be a versatile instrument: whether for relaxation and meditation or as an addition to percussion setups. With a size of 35.5 x 14 cm and a weight of 3.3 kg, the product sits comfortably on the lap, but can also be played on the floor or on a stand . The manufacturer offers nine different colors: black, dark blue, green, gold, blue, lilac, purple, white dotted and red. This variance allows an individual selection according to personal taste and preferences.

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.
