Milu
Muesli cup

The Milu muesli mug made a very good impression in our test. The product has an attractive, flawless design and is made of stainless steel that can be customised with engravings . Thanks to the insulation , both cold and hot food can be consumed at the desired temperature over a long period of time. The outside is always at a pleasant temperature in the hand. The pressure release valve makes it easy to open at any time, the non-slip base ensures a secure stand and the integrated spoon allows you to eat on the go. The muesli cup has a capacity of 400 or 200 ml and keeps the contents leak-proof . The mug can be cleaned by hand and is easy to clean thanks to the large opening and the enclosed care instructions.

Advantages

✅ Well thought-out concept
✅ double-walled insulation
✅ Leak-proof
✅ Two separate containers and integrated spoon
✅ Customised engraving possible

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.

Packaging

For our test, the Milu muesli cup arrived in a typical shipping box. 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 muesli pot was optimally protected from external influences and shipped hygienically. 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 maximum score is 100 points

The muesli cup consists of two separate containers – the insulated container and a transparent container for muesli, for example – as well as a folding spoon. Information on the use, safety and care of the product can be found on the product packaging and in instructions for use in 5 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.

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

Individual parts

First of all, the muesli cup makes a very good visual impression. We did not notice any manufacturing faults . 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 product also 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 that it will have 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

The food from the Milu muesli mug tasted very good in our test. This was mainly due to the fact that the thermo mug kept both cold and warm food (Bircher muesli, porridge) at the same temperature for a long time. The outside did not get hot or cold and was easy to transport. The product also scored points for its leakproofness, even though no silicone ring was used. The pressure release valve guarantees effortless opening and the non-slip base ensures a secure stand. The spoon supplied is easy to use and is the ideal size for the cup. The stated capacity of 400 or 200 ml was confirmed in our test. As the thermal container is not dishwasher-safe, the cup had to 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 navy blue, pink, black, turquoise and white 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 cut4.6 out of 5.0 on Amazon80 points
Total85 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.6 stars. One criticism is that the folding mechanism of the spoon becomes too loose after a while and cleaning is cumbersome . Other reviewers had none of these problems. Above all, they praise the design, the spill resistance, the ease of cleaning and the quality. We can fully endorse these opinions.

Prices of up to €63 are charged on the internet for equivalent products. Very inexpensive products, on the other hand, are available for as little as €15. This puts the Milu muesli cup in the middle price segment with a current price of €32.95. Consequently, the price ratio is very good for the quality and range of services you get.
