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?

The first impression of the self-adhesive felt glides is very good. They are delivered in a classic shipping box that protects the product well. Inside is the product box, which keeps the felt glides safe. The shipping paper also ensures optimum product protection. The packaging (shipping box) is made from recyclable, renewable materials and is therefore sustainable. The package contains 235 felt glides in various sizes and shapes, all in black.

Attaching the felt glides is very easy. The adhesive reaches its maximum strength after one hour. The felt glides protect surfaces very well from scratches and damage. They are versatile and suitable for various surfaces and furniture types. The set contains different sizes of round and rectangular felt glides. The felt glides are extra sturdy.

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*
Price / performance ratioVery good performance in the lower price segment90 points
Rating cut4.6 out of 5.0 on Amazon80 points
Total85 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.6 stars. One common complaint is that the adhesive surfaces come loose on heavy furniture. Many customers like the fact that many different sizes and shapes are available. In our practical test, we were able to confirm that the variety on offer was good. In our practical test, we did not find that the adhesive surfaces detached from the furniture.

Prices of up to €15 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €12. The felt glides from X-PROTECTOR are therefore currently in the lower price segment with a price of €12.61. The price-performanceratio isreasonable for the quality and performance received.
