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.

When handling the heat plaster for the first time, the visually appealing design immediately catches the eye. The high-quality workmanship gives a solid impression and suggests that the heat plaster is of good quality. The odour of the material is also neutral, which indicates that the raw materials have been carefully selected. The stability of the compress is also noteworthy, as it feels robust and can be attached to clothing in a stable manner. Although no specific information is given on the sustainability of the product, the use of high-quality materials indicates that IEA Medical attaches great importance to quality.

In our practical test, we found that the heat plaster from IEA Medical develops a pleasant warmth after approx. 5 minutes, which can be felt after a short time. The maximum temperature measured was 44°C, which is below the average temperature of 53°C specified by the manufacturer. Nevertheless, the heat remained constant for over 12 hours, which significantly increases wearing comfort. The heat was particularly effective when in close contact with clothing, such as a vest.

The heat plaster is comfortable to wear and does not cause skin irritation or restrict freedom of movement. Even after wearing it for a long time , it was hardly noticeable. A particularly positive aspect was that it left no adhesive residue on clothing after removal. No odour was detected either during or after use.
The heat plaster is very easy to use . The instructions for use are clearly structured, illustrated and enable effortless application. The packaging is compact, making the product ideal for travelling. However, a higher temperature development would be desirable in order to fully fulfil the manufacturer’s promises.
The heat plaster from IEA Medical offers a practical and reliable heat source for everyday use, even if the promised average temperature is not quite reached.

On the Amazon platform, consumers rate the product with an average of 4.2 stars. One common criticism is that the stated heat output of 53°C is not achieved. Many customers like the fact that the heat lasts for a long time and is easy to use. In our practical test, we were able to confirm that the heat output was good over 12 hours, but the temperature output did not meet expectations.

Prices of up to €23.60 are charged on the internet for equivalent products. Very cheap products are available from as little as €13.50 . The heat plaster from IEA Medical is therefore currently in the lower price segment with a price of €12.97. For the quality and performance received, the price-performance ratio is very good.
