Milu
Thermo mug large

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 and BPA-free plastic. The thermo mugs are available in different sizes. You can choose between a capacity of 370 ml or 450 ml. In our test, the mugs were absolutely leak-proof, even when tipped over and shaken, no liquid leaked out. Opening and closing the lid is very easy thanks to the so-called “One Click” closure. On request, Milu’s thermo mugs can also be engraved with the customer’s personalised text. This thermo mug is therefore also a great gift idea.

Advantages

✅ High-quality materials
✅ Double-walled insulation
✅ Shake and leak-proof
✅ Large selection of colours

Disadvantages

❌ Not suitable for dishwashers

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.

Product packaging

The Milu thermo mugs were 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 carton and the product packaging were easy to open. The product packaging is black and white.
The thermo mug was shrink-wrapped in a transparent plastic film. The film provides additional protection against soiling and damage during transport. 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 film around the cups, there is no unnecessary packaging material.
The cup packaging is partially recyclable. Unfortunately, the plastic film is not recyclable, but the Amazon cardboard box is.
Overall, the Milu thermo mug makes avery 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?

In addition to the thermo mug, the product box also contains the lid of the mug and a replacement seal for the lid. The set is complemented by a matching cleaning brush.
The instructions for use are very detailed and written in German and English. 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 both on the product packaging and in the additionally enclosed instructions for use.
Contact details can be found on the product packaging. These include the company name, the address, the name of the managing director and an e-mail address. Unfortunately, there is no telephone number. Please contact us if you have any queries or problems.
Overall, this is an extremely well thought-out and customer-friendly way of sending a product.

Thermo mugs in various sizes and colours

The Milu thermo mugs make a very good visual impression and have no manufacturing defects.
The thermo mugs are available in different sizes. You can choose between a filling quantity of 370 mlor 450 ml . The sizes of the mugs also differ accordingly. The thermal mug with a capacity of 370 ml is 17 cm high without the lid. With the lid, the total height is 20 cm. The thermo mug with a larger filling volume is 3 cm higher and therefore has a total height of 23 cm. The lid of both thermo mugs is 3 cm high. The lids are black with a coloured rubber strip. This coloured strip is exactly the same colour as the colour of the mugs. Just over 1/3 of the outside is covered in rubber. This coating is not only attractive to look at, but also keeps the hands at a pleasant temperature, regardless of whether the outside of the cup is hot or cold. Various coffee words are printed on the coloured rubber, such as: Coffee, Espresso, Milk etc., are embossed on the coloured rubber. There is a wide range of 10 different colours, so there is something to suit every taste. The thermo mug is made of high-quality stainless steel, which is free from harmful substances and is odourless and tasteless. Another advantage is the mug’s low weight of just 325/360 grams and the sturdy, high-quality finish.
The cleaning brush supplied consists of two individual parts that can be put 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 the thermo mugs with boiling water in the morning. Even after our test phase of approx. 9 hours, the filled liquid was still very warm and hardly lost any temperature. The outside was neither hot nor cold and was therefore comfortable to hold. In our test, the cups were absolutely leak-proof, even when tipped over and shaken, no liquid leaked out. We can also confirm the stated filling quantities of 370ml and 450ml after our test.
Opening and closing the lid is very easy thanks to the so-called “One Click” closure. All you have to do is press the button in the centre of the lid. If the button is pressed down, the lid is open and the drink can be consumed. If, on the other hand, the button is at the top, the lid is closed and sealed. This difference is clearly visible.
The lid can be disassembled into two parts for cleaning. To take the lid apart, turn the inner lid to the right. After cleaning, the lid is reassembled in the opposite direction. To make this easier, the opening/closing direction is engraved on the lid. The lid can also be cleaned in the dishwasher. The cup itself is not dishwasher-safe. Due to the material used, cleaning in the dishwasher is not possible, as is the case with other thermal containers. The thermo mug should be stored with the lid open when not in use.
On request, Milu’s thermo mugs can also be engraved with a personalised text of the customer’s choice. This thermo mug is therefore also 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 analyse consumer reviews and check whether the critical and positive reviews are actually justified.

Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.6 stars. The old lid of the cup is often criticised. As this lid has been replaced and replaced with a new lid, the reviews are no longer valid. Many customers like the fact that the cups are leak-proof. The insulation and therefore how long the drinks stay warm is also praised. We were able to confirm this in our practical test.

Prices of up to €39.75 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €11.90. The Milu thermo mug is currently in the mid-price segment with a price of €19.95/€21.95. The price ratio is good for the quality and the range of services you get.
