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 maximum score is 100 points

The product receives an average of 4.7 stars on Amazon. Customers praise the intense freshness and opening of the airways. However, it is pointed out that the crystals can smoke if they get too hot. Our tests confirm the high concentration and the need to crush the crystals, especially in smaller saunas. We have not tested the use in water. The quality of the product and the natural ingredients are rated positively. The packaging is practical and preserves the freshness of the crystals. In summary, LoWell® menthol crystals are an effective solution for a refreshing sauna experience, but should be used with care, especially in smaller saunas.

Prices of up to €55/100g are charged on the internet for equivalent products. Very inexpensive products are available from as little as €6.99/100g . The menthol crystals for the sauna from LoWell® are therefore currently in the lower price segment with a price of €14.95/100g. The price-performance ratio is reasonable for the quality and performance received.
