Milu
Thermo container

The Milu thermal container made a very good impression in our test. The product has an attractive, flawless design and is made of stainless steel and BPA-free plastic. There is a large selection of 7 different colors, so there is something for every taste. The word “Milu” is embossed in silver in the lower third. A total of 5 carrying straps in different colors are included. This allows you to distinguish the cups at first glance and change the color depending on your mood. You can choose between 450 ml, 650 ml and 800 ml filling volumes . Opening the container is very easy thanks to the integrated pressure relief valve.
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. On request, Milu thermo mugs can also be engraved with the customer’s individual text. This also makes the thermo mug a great gift idea.

Advantages

✅ High-quality materials
✅ Double-walled insulation
✅ Shake and leak-proof
✅ Large selection of colors and individual engraving possible

Disadvantages

❌ Not suitable for dishwashers

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.

Shipping carton

The Milu thermal container was delivered together with other products in a single shipping box. The shipping carton was compact and the individual products had little room to move around. The remaining space in the shipping carton was therefore filled with recycled paper filling material. 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 black and white.
The container is wrapped in transparent bubble wrap. The film provides additional protection against soiling and damage during transportation. The thermal container is also packed in a fabric bag. The cleaning brush is also wrapped in extra foil. As the product packaging is sufficiently robust, we believe that the film could have been dispensed with. Overall, the set is well protected in the packaging and, apart from the foil, 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 carton can.
Overall, the thermal container makes a very good impression.

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?

*The maximum score is 100 points

The product box contains the thermal container with lid including 5 different carrying straps and a spoon. The set is complemented by a matching cleaning brush and a replacement seal as well as a gray fabric bag. The instructions for use are very detailed and written in German and five other languages. In addition to the instructions for use, there is further information on care and cleaning as well as safety instructions. These recommendations for use can be found on the product packaging.
Contact details can be found on the product packaging. Contact details can also be found on the bottom of the container. These include the company name, the address, the name of the managing director and an e-mail address. Unfortunately, there is no telephone number. If you have any queries or problems, please contact us.
All in all, this is an extremely well thought-out and customer-friendly way of sending a product.

complete content

The thermal containers from Milu make a very good visual impression and have no manufacturing defects.
The containers are available in different sizes. You can choose between 450 ml, 650 ml and 800 ml filling volumes. The sizes of the containers differ accordingly. The small thermos jug with a filling volume of 450 ml has a height of 16 cm. The medium size with a filling volume of 650 ml has a total height of 19 cm. The largest container is 21 cm high and holds 800 ml. There is a wide range of 7 different colors, so there is something for every taste. The lettering “Milu” is embossed in silver in the lower third. The lid is grey, whereas the cup is colored. This coating is not only nice to look at, but also keeps your hands at a pleasant temperature, regardless of whether the outside of the cup is warm or cold. The already threaded carrying strap has the same color as the mug. However, it can be exchanged for the other carrying straps supplied. A total of 5 different colored carrying straps are included. This means that the mugs can be distinguished at first glance and the colors can be changed to suit your mood.
The thermo mug is made of high-quality stainless steel, which is free from harmful substances and is odorless and tasteless. Another advantage is its low weight and the sturdy, high-quality finish.
The cleaning brush supplied consists of two individual parts that can be pushed together with a little pressure. The height of the brush is ideal for cleaning the base of the cup. This avoids the problem of hands being too wide to clean the entire cup.

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

For the test, we filled a warm soup into the thermo containers in the morning. Even after our test phase of approx. 8 hours, the liquid was still very warm and 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 specified filling quantities of 450ml, 650ml and 800ml after our test.
Opening the container is very easy thanks to the integrated pressure release valve. The pressure can be released by pressing down 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 itself is not dishwasher-safe and should be cleaned by hand. Due to the material used, cleaning in the dishwasher is not possible, as is the case with other thermal containers. The warming containers should be stored with the lid open when not in use.
On request, Milu containers can also be engraved with an individual text of the customer’s choice . This also makes the thermos jug a great gift idea.

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.

Rating cut4.7 out of 5.0 on Amazon85 points
Total88 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.7 stars. One criticism is that the container occasionally leaks or that the product arrived incomplete. Other reviewers, however, have no negative comments. They praise the design, leakproofness, ease of cleaning and quality. After our practical test, we can wholeheartedly agree

Prices of up to €40.46 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €20.00. With a price of €25.95-€30.95, the Milu thermal container is currently in the mid-price segment. The price ratio is good for the quality and scope of services you get.
