The first impression

Packaging and contents

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 guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The thermos flask is carefully packaged. The sturdy cardboard box offers sufficient protection during transportation. The sustainability of the packaging is particularly noteworthy. We have deliberately avoided unnecessary packaging waste and the use of plastic. The product packaging contains a thermos flask (750 ml) in the color Desert Sage. There is also a leaflet with instructions for use in ten languages (German, French, English, Spanish, Portuguese, Italian, Polish, Dutch, Swedish and Danish).

Unboxing

The thermos flask is characterized by an appealing, elegant design and is made of stainless steel. The workmanship is very good, with no visible defects such as scratches, dents or unclean transitions. The materials used make a robust and stable impression. In terms of sustainability, care was taken during the production of the thermos flask to ensure that the CO₂ produced was offset via a climate protection project (Virunga National Park), which is why the product is labeled as climate-neutral . Due to the high-quality materials, we assume a long service life, which minimizes the use of disposable products.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

We really liked drinking from the MAMEIDO thermos bottle during the test. This was mainly due to the fact that the thermos flask 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. The product is also unbreakable, leak-proof, tasteless and food-safe. The lid is 100% leak-proof on the go. The stated capacity of 750 ml was confirmed in the test. As the thermos flask is not dishwasher-safe, it had to be cleaned by hand.
Customers can currently choose from the colors Black Marble Gold, Carbon Grey, Crystal Black, Crystal Rose, Crystal Sand, Desert Sage, Ivory Beige Gold, Oak Wood Gold, Pearl Marble Gold, Powder Blush, Rich Black, Rosé Quartz, Taupe Grey, Taupe Grey Gold and White Marble Gold, the model with or without engraving and a capacity of 500, 750 or 1000 ml .

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine 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 look at the consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good performance in the lower price segment90 points
Rating cut4.5 out of 5.0 on Amazon75 points

Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.5 stars. Customers praise the outstanding quality, functionality and impressive appearance. Some users initially had problems screwing the bottle on properly.

Prices of over €100 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €13 . The MAMEIDO thermos flask (750 ml) is therefore currently in the lower price segment with a price of €29.99 . For the quality and performance received, the price-performance ratio is very good.
