Review for model:

Good quality workmanship. I poured boiling water and after 12 hours the drink was still warm. The only downside is the height – it's a bit too tall, but after all, it's a liter. I bought it on promotion, so the price compared to the quality is excellent.

Narrow and tall (personally, I thought it wouldn't be so tall, because that's what I actually wanted). As for "keeping" the warmth, I haven't tested it yet. Besides that, the mug lid came slightly dented, but that's probably the courier's fault (probably...).

A really solid thermos—I bought it some time ago and I can confidently say that for this price it's great. Coffee and tea stay warm for a long time. I can highly recommend it.

I am adding a photo with a temperature test after 7 hours. The thermos was half-full of tea, the temperature was 53 degrees Celsius. I rate it as very good. The promotional price is attractive.

After four hours, the tea is hot; after seven hours, half the thermos is still filled with tea. I did a test—over 50 degrees Celsius. The promotional price is low. I rate the thermos as good quality and it keeps the heat well.

The coffee inside stays warm for many hours. The thermos is sturdy and large, with a capacity of one liter. Perfect for a whole day at work or outdoors. I recommend it.

A decent metal thermos. Good quality craftsmanship, overall aesthetically pleasing. Heat retention is as specified. Comfortable pouring and use. A good option when it comes to liter-size thermoses. I recommend it.

The thermos is very tight. I have used it both for hot tea (after 8 hours at an ambient temperature of 15°C, it was still so hot that you couldn't drink it right away) and for cold drinks in the summer. I pour a drink from the fridge, add 15 ice cubes, and after 6 hours (at an ambient temperature of 26°C) there's still ice floating in the thermos. Super extra!
