In my closet there are so few of these things that you can use at most times for afternoon tea / coffee. After 1-2 hours, most drinks are only lukewarm. Not what I expect.
Until the bottle Salewa times in the flash range. The price was good and so is Amazon. Since you can order and when it really is not good also return without much effort and trouble. I like that about Amazon.
2 or 3 days later the package arrived already. Because XMAS times 1 day later than usual, but is indeed OK.
Aside from the color (wems like) is processed the bottle clean. Outside of spring steel, which gives a bit under load and therefore not so easy dents leaves as other materials and stable as well. Well, Salewa's also outdoor brand.
Cover and closure sit clean and the valve opening and closing can be split largely what makes cleaning easier. Exemplary.
The interior consists of stainless steel. Insensitive to stains, impacts, etc. Since you can also safely times with pure ice throw. Do not go for many other vacuum bottles because of the glass inner life indeed.
A first test: Morning tea with pure and put in the work. At noon the tea was so hot that I burned myself for now. Bad for me, good for a thermos.
Also in the evening about 18.00 clock, so after a good 10 hours my tea was still hot. Because of the constant opening and closing, and because not more as much liquid in it was, of course, not excessively, but adequate.
I'm happy and expectant keep the thermos!
UPDATE:
I've got the bottle now or 2 years and it still looks like new. Of course, they had now already with into the mountains for hiking and skiing and also in cold outdoor temperatures keeps them quite properly what it promises. Drinks stay hot and reliable in the bottle. The seals and the valve working properly!
