1. Thermal power: after 18Std. still warm
2. quality of stainless steel: easy to clean and is not prone to stains that are difficult to remove (Have a Edelstahlkuehlschrank of a renowned brand in the not so is)
3.Hygiene: lid opened when pouring, content must not labyrinth which is difficult to clean. Opening is a bit small, so with dr hand is not pure one, but you can clean the pot with a brush or in the dishwasher.
4. Toxins: quality workmanship outside as inside stainless steel, beverage does not come into contact with plastic (for plasticizers). While the cover is a plug made of plastic, but Who cares can get drehn him even. Seal is made of rubber.
5. Warranty: 5 years
6. Design: I am delighted every time I use the jug!
7. Usability: grip was never hot! At most hot even after prolonged holding of even boiling water (maybe that can also be improved because the heat better then remains in the pot), pot does not drip due form when pouring, an extreme vacuum when cool I could not find, perhaps was it difficult to minimal, but not worth mentioning.
CONCLUSION: I love this pot and would unreservedly recommend it to everyone, even if it is not exactly cheap, it is worth it to spend a little more for it and to have something good!
