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.

Werkthor
Car ramps

The Werkthor drive-on ramps have proven to be a very space-saving, yet very useful and stable car accessory. As the two ramps can be stacked inside each other, they can be hung in a corner or on a wall at any time and are still ready for use in seconds. The product is not CE-certified, but has withstood a VW Golf 7 Variant with a weight of approx. 900 kg on the front axle without any problems. The studs and the underbody covering of the ramps ensure that the car can drive over them without slipping.

  • Stackable
  • Very stable
  • Non-slip and high quality
  • No recognisable CE certification

The first impression

Packaging and contents

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 product is delivered in a sturdy but optimally designed box. A positive feature is that the product is packaged without any plastic film, so that it can be removed directly from the box and is theoretically ready for immediate use. An instruction manual is not included, but is not necessary due to the use of the ramps and is not considered necessary.

The product design is very well thought out both on the work surface and under the ramps. There are several knobs and slip mechanisms on the ramp so that the product could also be used in snow. The workmanship was clean all round with no possible damage and it was also very stable. No information was provided on the durability of the product. However, due to the high quality of workmanship, it can be used in the long term.

In practical testing, the product clearly proved to be an inexpensive but very useful and very safe workshop aid. A VW Golf 7 Variant with a front axle load of approx. 900 KG could be placed on the ramps without any problems and without any danger at any point. Not the slightest slipping or instability could be detected. No creaking could be detected either, meaning that the access ramps were comparatively quieter than steel access ramps. Stepless lowering with several short stops is possible without any problems thanks to the many knobs. The product can be transported in a matter of seconds thanks to its stackability and very lightweight design. The product scored highly on all five test points.

Price/performance ratio

and ratings from consumers

Finally, we analyse 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.

*Themaximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.2 stars. In individual cases, there is criticism that it is not felt to be secure enough. On the other hand, the non-slip and stable design and the high holding power are emphasised positively. In our practical test, we were able to confirm that the non-slip and stable design of the ramps is well received by customers. However, consumer criticism of the possible lack of stability was not justified.

Prices of up to €79.90 are charged on the Internet for equivalent products. Very affordable products are available from as little as €56.90 . The Werkthor drive-on ramps are therefore currently in the lower price segment with a price of €59.99. For the quality and performance received, the price-performance ratio is very good.
