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.

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?

Our practical test has shown that ZENAPHYR menstrual underwear is suitable for moderate bleeding . The briefs offer reliable protection for up to 12 hours. The innovative 4-layer technology effectively prevents wetness and leakage. Although the sewn-in pad is slightly thicker than comparable products, this does not affect the wearing comfort. The menstrual underwear is available in various sizes from XS to XXL . The corresponding measurements for the individual size can be found on the sales page. The product has an odour-neutralizing and antibacterial effect. It also respects the pH value of the intimate area. Cleaning the menstrual underwear proved to be uncomplicated. The briefs can easily be washed in the washing machine at 30°C .

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*

Rating cut4.1 out of 5.0 on Amazon60 points

*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.1 stars. Customers like the fact that the underwear fits comfortably despite the initial tightness and offers reliable protection, especially in the case of moderate bleeding . The absorbency and odour neutralization are impressive, and the environmentally friendly, sustainable production is praised. However, several customers complain that the fit is too small in their case.

Prices of up to €40 are charged on the Internet for equivalent products. Very affordable products are available from as little as €18 . The menstrual underwear from ZENAPHYR is therefore currently in the middle price segment with a price of €29.99. For the quality and performance received, the price-performance ratio is good.
