I was choosing a not-too-expensive thermos since I don't need to use it often (1-2 times a month at best). I liked this one for its reasonable price, attractive design, and decent features. The flask is made of steel, so the thermos isn't afraid of bumps and falls (before this, I used a thermos with a glass flask that shattered to pieces on the first drop). The design is classic, but the black insert caught my attention – it looks cool. Plus, it turns out that this insert makes the thermos much easier to hold.

After using it a little, I can say the thermos is not bad. Of course, it doesn’t break any temperature retention records, but it's suitable for the needs of an average person. For instance, if you pour fresh hot coffee in the morning, it maintains the temperature until the evening without significant loss. I can't say for sure, but in my observation, it loses only about 20 degrees of warmth over 10 hours. To me, that's an excellent result for an affordable thermos. Cold drinks fare even better – they don't warm up at all during the day (well, maybe just a little).

The lid doubles as a decent cup. Most importantly, it doesn't heat up at all, so you can drink from it confidently.
