For 1.5 months after the purchase, they used a thermos 4-5 times. He kept the declared temperature regime only 1 time. The second time did not last even 12 hours. All other times it cooled down in 4 hours. I do not recommend to buy. I was pleasantly surprised when the Arctic team represented by expert Alina responded to my review. In the course of communication, it turned out that the thermos I bought turned out to be defective and they replaced it for free. I thank the Arktika company for their sensitive attitude towards their customers.
I wanted to give a more comprehensive review, so I included some photos.
