Packaging
For our test, the Milu thermos flask 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 thermos flask 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.

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 thermos flask during the test. This was mainly due to the fact that the thermos flask kept both cold and warm liquids at the desired temperature over a longer period of time. The outside was neither hot nor cold and was comfortable to hold. A carry bag is included for easy transport, which can be clipped on or off. The lid is 100% leak-proof when travelling. The stated capacity of 350, 500, 750 or 1000 ml was confirmed in our test, but we did not have the 1500 ml version. As the thermos flask is not dishwasher-safe, it had to be cleaned by hand. This is child’s play thanks to the cleaning brush supplied and the enclosed care instructions.
Customers can currently choose from the colours berry, buttercream, granite, grey, green, marble, mint, navy blue, olive green, pink, rose gold, red, black and stainless steel 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.
| Criterion | Remark | Points achieved* |
|---|---|---|
| Price / performance ratio | Very good | 95 points |
| Rating cut | 4.8 out of 5.0 on Amazon | 90 points |
| Total | 93 points |
*The maximum score is 100 points
On the Amazon platform, consumers have given the product an average rating of 4.8 stars. One criticism is that the carrier bag does not fit and the lid twists after a while. Other reviewers, however, do not share this criticism. They praise the design, the leakproofness, the ease of cleaning and the quality. We can fully agree with this.
Prices of up to €80 are charged on the internet for equivalent products. Very inexpensive products, on the other hand, are available for as little as €10. The Milu thermos flask is therefore in the lower price segment with a current price of €20.95 – €37.95. Consequently, the price ratio is very good for the quality and scope of services you get.
