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 Diamond Painting sealant from Valunique impresses with its high-quality finish the first time you pick it up. The visual appearance is appealing and testifies to the attention to detail. The product impresses with its high stability, which indicates a long service life and robustness. Unfortunately, there is no specific information on the sustainability of the product, which could possibly be a point of criticism for environmentally conscious consumers. Another advantage is that the packaging is also suitable for giving as a gift. The product is therefore particularly suitable as a gift idea.

The practical test has shown that the manufacturer’s Diamond Painting sealant fulfils its advertising promises. The diamonds adhere firmly to the canvas thanks to the strong adhesion, while the appropriate drying time of at least 60 minutes enables the work to be completed quickly . The glossy effect of the sealant ensures optimum presentation of the colours and details of the diamond painting. The long-term durability is also impressive, protecting the artwork from external influences such as dust or moisture. The simple application with a brush and a container, even if these are not included in the scope of delivery, makes the sealant a recommended choice for all hobby artists. Overall, we can recommend the Diamond Painting sealer as a reliable and high-quality product.

*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.8 stars. A frequently mentioned point of criticism is that no brush and container are included in the scope of delivery, which makes application more difficult. On the other hand, the ease of application of the sealant is emphasised positively, with many customers describing it as excellent. In our practical test, we were able to confirm that the adhesion of the diamonds and the glossy effect of the sealant were convincing, while the lack of a brush and container was actually perceived as a disadvantage.

Prices of up to €18.99 are charged on the Internet for equivalent products. Very affordable products are available from as little as €13.49 . The sealant from Valunique is therefore currently in the lower price segment with a price of €14.95. For the quality and performance received, the price-performance ratio is very good.
