Milu
Thermo mug

The Milu thermo mug made a very good impression in our test. The product has an attractive, flawless design and is made of stainless steel, which can be customised with engravings , and BPA-free plastic. Customers can choose between two lids depending on their requirements. Thanks to the insulation , both cold and hot drinks can be drunk at the desired temperature over a longer period of time. The outside always feels pleasantly warm in the hand. The thermo mug has a capacity of 210 ml and is leak-proof . However, the “One Click” closure protrudes further into the cup and therefore only allows for around 190 ml. Both closures are dishwasher-safe. However, the stainless steel cup must be cleaned by hand.

Advantages

✅ Handy size
✅ Double-walled insulation
✅ leak-proof
✅ Two different lids
✅ Customised engraving possible

Disadvantages

❌ Only partially dishwasher-safe
❌ Capacity depends on the lid

The test

General information

We have looked at and tested the product in detail in a practical test. In the following, we take a closer look at the features and impressions. The product is subjected to our test procedure from the packaging, materials and quality to the range of functions and handling.
To give you a quick overview, we work with a points system. The maximum possible number of points per area is 100 points. The final overall score is calculated from the average of all tested features, taking into account the respective weightings. For a detailed insight into our comprehensive evaluation process, which forms the basis of all our product ratings, please click here.

The first impression

The packaging and labelling

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

The Milu thermo mug came in a typical shipping box for our test. This was undamaged on arrival and could be easily opened by removing the adhesive strip. Inside the product box, the product was wrapped in plastic film. This type of packaging ensured that the thermo mug was optimally protected from external influences and hygienically dispatched. Product protection was therefore fully guaranteed and the product was delivered in perfect condition .
The packaging is partially recyclable. However, the plastic film cannot be recycled . Nevertheless, the presentation of the product 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 pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The thermo mug comes with two different lids – one with a flip-top closure, the other with a “one click” closure. Information on the use, safety and care of the product can be found on the product packaging and in the instructions for use in two languages.
Contact information can be found directly on the product and on the product box. An email address and Instagram page are provided, but there is no customer hotline. Nevertheless, this is a very good way to send a product.

two lids

First of all, the thermo mug makes a very good visual impression. We did not notice any manufacturing defects . Furthermore, all the transitions are clean and there are no scratches or edges to be seen. The insulated part is made of stainless steel and can be personalised with an engraving. The lids are made of BPA-free plastic and can be cleaned in the dishwasher. The product impresses with its simple, timeless design.
There is no information about the sustainability of the product. However, 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 really enjoyed drinking from the Milu thermo mug during the test. This was mainly due to the fact that the thermo mug kept both cold and hot liquids at the desired temperature over a longer period of time. The outside did not get hot or cold and was comfortable to hold thanks to the rubber coating. Customers can choose between two lids depending on their requirements. Both guarantee leakproofness. We can only confirm the stated capacity of 210 ml for the flip-top lid. The “One Click” closure protrudes further into the cup and can therefore only hold around 190 ml. Both closures are dishwasher-safe. However, the stainless steel cup must be cleaned by hand. This is child’s play thanks to the large opening and the enclosed care instructions.
Customers can currently choose from the colours blue, brown, grey, green, mango, olive green, pink, red, black, turquoise and purple and the model with or without engraving .

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.

CriterionRemarkPoints achieved*
Price / performance ratioVery good90 points
Rating cut4.4 out of 5.0 on Amazon70 points
Total80 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.4 stars. One criticism is that the heat output is not sufficient and warm drinks lose temperature after a short time. Other reviewers, however, are satisfied with the insulation. They also praise the design, leakproofness, ease of cleaning and quality. We fully agree with this, although the capacity of the “One Click” cap should be adjusted in the product description.

Prices of up to €32 are charged on the internet for equivalent products. Very inexpensive products, on the other hand, are available for as little as €10. This puts the Milu thermo mug in the middle price segment with a current price of €17.95. Consequently, the price ratio is very good for the quality and scope of services you get.
