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
Drive-on wedges

The Werkthor wheel chocks made a good impression in our test. The product is an innovative round wedge that offers infinitely variable height compensation and tire-protecting stability. The shape of the Werkthor round wedge is perfectly match ed to the curve of the vehicle tire. Homogeneous driving on and safe standing are guaranteed, an additional drive-on aid is not necessary.
There are no unpolished edges or manufacturing defects on the product.

Advantages

✅ Innovative round wedge
✅ Stepless height compensation
✅ No additional drive-on aid required

Disadvantages

❌ No hotline available

The first impression

Packaging and labeling

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 ensured.

Packaging of the drive-on wedges

The Werkthor drive-on wedges arrived in the typical Amazon box. The box was undamaged and easy to open by removing the parcel tape. The drive-on wedges were packed in a bag inside the box. The product protection was complete in this case and the wedges were therefore in perfect condition.
The packaging of the product is fully recyclable.
On the whole, the Werkthor drive-on wedges make a very good impression. The wedges were not damaged and the package was in good condition.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

After unpacking, there were five things on the table. In addition to the two round wedges, two chocks and a matching plastic bag were included. Instructions for using the product can be found on the enclosed instructions for use. Contact information is provided, the only thing missing is a customer hotline. All in all, this is an extremely well thought-out and customer-friendly way to send a product.

The first time in your hand

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

CriterionRemarkScore achieved*
Visual appearanceGood visual appearance90 points
ProcessingGood workmanship, no edges or defects90 points
StabilityProduct appears very stable90 points
Sustainability of the productNo information on sustainability – however, we assume a long service life due to the materials used80 points

*The maximum score is 100 points
The wheel chock and the wheel chock

Both the wheel chocks and the wheel chocks are made of sturdy plastic with a textured surface for better grip. The plastic protective cover included in the package should be emphasized. This prevents damage after use and ensures safe and tidy storage.
The customer is supplied with high-quality drive-on wedges that can serve him well.
Unfortunately, there is no information about sustainability on the Amazon product page or on the packaging. Due to the high-quality materials used, we assume a long service life.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

We enjoyed using the Werkthor drive-on wedges during the test. It is very easy to drive on without an additional person. Thanks to the corrugation of the wheel chocks and the wheel chocks, the two interlock perfectly, preventing the chocks from slipping. Use on an unpaved surface is not necessarily recommended, as the contact surface is too small.
In short, it is a great product for quickly and easily leveling your motorhome or caravan on uneven surfaces.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at 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 examine consumer ratings and check whether the critical and positive reviews are actually justified.
