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.

IDEM RADICES
Knot practice set

The knot practice set from Knotenstunde made a very good impression in our test.
The product is a comprehensive knotting course for the recreational boating licence for sea and inland waterways as well as the Bodensee boat licence. It contains 11 knot cards with step-by-step instructions, a video course, a boat cleat with suction cups, two ropes and everything you need for the exam. By purchasing this product, you are supporting a young company that specialises in durable products with optimum customer benefits. Unfortunately, the cards are not waterproof , which means that they can only be used (the flashcards) in dry places. On the positive side , the well-designed video course should be emphasised.
Overall, the knot practice set from Knotenstunde is a highly recommended product.

Advantages

✅ Beautiful video course + instructions
✅ Practical bag for storage
✅ Boat cleat with suction cups

Disadvantages

❌ No customer hotline available on packaging

The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. Of course, adequate protection of the product must also be ensured.

Packaging of the knot training set

The knot practice set from Knotenstunde arrived for our test in a typical shipping box, which was easy to open by removing the adhesive strip and arrived undamaged .
The box contained the storage bag wrapped in bubble wrap with the instructions, two ropes and the boat cleat.
Unfortunately, plastic was used to protect the product from soiling . In this case, the product was fully protected and the training set was therefore in perfect condition.
The packaging of the knot practice set is unfortunately not fully recyclable.
The first impression is very good, as neither the product nor the packaging used was damaged.

After unpacking

Package contents and instructions

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

*The maximum score is 100 points

After unpacking, the knot practice set with a carrier bag, 11 instructions, two ropes and a boat cleat lay on the floor of the living room. The instructions for the individual knots are very easy to understand. They offer the customer the opportunity to learn the knots in detail.
Unfortunately, the customer is not offered a customer hotline as a contact option. However, the customer has the option of sending a letter or e-mail to the company using the address provided. This information is printed directly on the outside of the packaging and can be easily viewed by the customer.
Overall, we still consider this to be a good shipping method.

The knot training set from Knotenstunde makes a very good visual impression in the test. In addition to the simple design, it has no manufacturing faults.
The product impresses with its reasonable weight and good workmanship. The ropes and the boat cleat are very stableand can withstand even heavy loads.
The customer is supplied with a knot practice set that can provide good service.
Unfortunately, there is no information about sustainability on the Amazon page or on the packaging. Nevertheless, due to the high-quality materials used, we assume a high level of durability.

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

In our practical test, we extensively tested the knot course for the recreational boating licence lake + inland and the Lake Constance boat licence. With a total of 11 different knots , it offers a comprehensive range to be well prepared for the exam .
We found the included video course, which shows all the knots in detail, particularly practical. This allowed us to memorise the knots not only by reading the instructions, but also by watching the videos. The course is very comprehensive and goes into every detail. This made it easy for us to copy and practise the knots. It should be noted, however, that the cards are unfortunately not waterproof , so you have to make sure you practise in dry places .
The supplied boat cleat with suction cups is very robust and holds well on all smooth surfaces. The ropes supplied are long enough to practise and test the full size knots .
The large bag contains everything you need for the test.
Overall, we are very satisfied with the knot course.

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 analyse consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*

Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.5 stars. One criticism is that the writing on the cards is small and the suction cup does not stick to all surfaces. Many customers like the included video course, the storage bag and the completeness of the set. In our practical test, we were also able to confirm these points, although we found the writing on the cards large enough to read everything.

Prices of up to €25 are charged on the Internet for equivalent products. Very inexpensive products are available for as little as €9. With a price of €15.90, the knot training set from Knotenstunde is currently in the middle price segment. The price ratio is good for the quality and scope of services you get.
