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.

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 thermos jug impresses with its good looks and high-quality workmanship. The double-walled vacuum insulation ensures good insulating performance. The carrying handle is practical, but the lid is not particularly sturdy. The jug itself is stable overall and appears robust. There is no information available on the sustainability of the product, but the use of stainless steel and theease of cleaning indicate a certain degree of environmental compatibility.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. 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 were able to confirm that the Dimono® 2 liter thermos jug delivers what it promises.
The insulation performance is very good and the jug keeps drinks hot or cold for several hours.
The easy handling of the one-click closure makes it uncomplicated to use. Cleaning is also easy, although the jug is not dishwasher-safe. To make cleaning easier, the top part of the jug can be unscrewed so that the inside of the jug can be cleaned easily.
The jug is leak-proof and did not leak any liquid during our test. However, the plastic lid does not seem as sturdy as the rest of the product.
The carrying strap does not make a very stable impression. This is not a problem when the jug is empty, but we would not trust the secure hold when it is full.
Overall, the Dimono® thermos jug offers very good value for money and is a recommended choice for anyone looking for a reliable and versatile thermos jug.

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 ratioAppropriate80 points
Rating cut4.0 out of 5.0 on Amazon50 points
Total65 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the Dimono® 2-liter thermos jug with an average of 4.0 stars. The excellent insulation performance and practical handling are frequently praised. However, some customers criticize the lack of stability of the lid and the fact that the plastic base is not particularly durable. In our practical test, we were able to confirm the positive aspects, but we recommend a possible revision of the closure to increase stability.

Prices of up to €59.36 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €23.99. The 2 liter thermos jug from Dimono® is therefore currently in the lower price segment with a price of € 23.99. The price-performance ratio is reasonable for the quality and performance received.
