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.

Dimono®
Thermo container

The Dimono® thermal container made a very good impression in our test. The product has an attractive, flawless design and is made of high-quality stainless steel and BPA-free plastic. The container is very easy to open thanks to the integrated pressure relief valve. The non-slip rubber base is also very practical. The container can be tested for 30 days without obligation. The removable outer lid, which is designed as a bowl, enables practical portioning and is therefore ideal for on the go. The retractable spoon is particularly practical. The container is available in 2 different sizes. Unfortunately, it is not dishwasher-safe.

Advantages

✅ Keeps hot for up to 10 hours and cold for 16 hours
✅ High-quality materials
✅ Double-walled insulation
✅ Shake and leak-proof

Disadvantages

❌ Not suitable for dishwashers

The first impression

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?

Weighting: 20%
*The maximum score is 100 points

The Dimono® thermal containers were delivered in a common shipping box. The shipping carton was compact and the individual products had little room to move around. The product packaging was undamaged and in perfect condition. Both the shipping box and the product packaging were easy to open. The product packaging is beautifully printed.
The container is wrapped in a transparent film. The film provides additional protection against dirt and damage during transportation. Overall, the set is well protected in the packaging and, apart from the film, no unnecessary packaging material has been used.
The packaging of the container is partially recyclable. Unfortunately, the plastic film cannot be recycled, but the product box can.
Overall, the thermal container makes a very good impression.

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the workmanship of the products. How high quality are the materials used? Are the look and feel satisfactory?

*The maximum score is 100 points

The Dimono® thermal container makes a very good visual impression and has no manufacturing defects.
The containers are available in different sizes. You can choose between 500 ml and 700 ml filling volumes. The container sizes differ accordingly. The small thermos jug with a filling volume of 500 ml has a height of 13 cm. The large container is 16 cm high.
The thermo mug is made of high-quality stainless steel, which is free of harmful substances and is odorless and tasteless. The elegant packaging already suggested a high-quality product. The product itself impressed with its excellent workmanship and showed no defects or sharp edges. The container is made of robust stainless steel and feels good to the touch. The workmanship of the Dimono® thermal container is impressively high quality. In addition, the container is stable on the table and therefore safe to use. Another aspect that speaks for the sustainability of the product is its durability thanks to the use of high-quality materials. Dimono® focuses on quality.


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

For the test, we filled a warm soup into the thermo containers. Even after our test phase of approx. 9 hours, the liquid was still very warm and had hardly lost any temperature. Even cooled liquids remained cold for a long time. The outside was neither hot nor cold and was comfortable to hold. The container proved to be absolutely leak-proof in our test; no liquid escaped even when tilted or shaken. We can also confirm the stated filling quantities of 500ml and 700ml after our test.
Opening the container is very easy thanks to the integrated pressure release valve. The pressure can be released by pressing the button. The removable outer lid, which is designed as a bowl, allows practical portioning and is therefore ideal for on the go. Filling is also easy. The non-slip rubber base of the container ensures a secure stand.
The retractable spoonis particularly practical. It has a fixed place in the recess of the screw cap. This means it cannot slip and is ready for use when needed without having to search for it. The spoon is easy to open and is a convenient size for eating.
The lid is dishwasher-safe. The thermos flask itself is not dishwasher-safe and should be cleaned by hand.

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.

Weighting: 15%
*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 container occasionally leaks. However, other reviewers have no negative comments on this. They praise the design, leakproofness, ease of cleaning and quality. After our practical test, we can fully agree with this

Prices of up to €40.46 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €17.00. With a price of €18.99/€19.99, the Dimono® thermal container is currently in the mid-price segment. The price ratio is very good for the quality and scope of services you get.
