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.

Swiss Activa+
Silent Hula Hoop S4.S

The Silent Hula Hoop S4.S from Swiss Activa+ revolutionizes classic hula hoop training. The clips of the individual segments snap securely into place and hold them together in a stable and tear-resistant manner. The device is suitable for beginners and advanced users with a waist circumference of 60 to 112 cm. During training, the 430 g rubber ball moves around the body on an adjustable cord and the revolutions are measured using a digital progress counter.

In addition, a 7-day training program in English can be accessed via a QR code.
