- Well-known company. The label says it has a 5 year warranty. There are no foreign smells. It keeps the temperature normally, as stated in the characteristics - at room temperature: poured boiling water, after 12 hours poured out very hot water (burns the hand).
- The plug worries a little: it is an original design with a pressure lever and a rubber bellows rubber valve seal. The lever, if used carelessly, can break off, and the bellows seal of the valve can break. It is unlikely that you will be able to buy the same cork separately. The cork is screwed onto the neck along the external thread, which does not look very reliable, it is not always possible to screw it on the first time without skew, there is a feeling that the thread has been torn off. In general, they overdid it with the valve. It would be better if they made a rotary plug, like in "Termos" or "Arktika", it would be more practical, at least you can buy a spare plug for them.
