Maestro MR1630-50 0.5 L

I chose a not too expensive thermos, since there is no need to use it often (1-2 times a month at best). I liked this one for its reasonable price, nice design and normal characteristics. The flask here is steel, which means that the thermos is not afraid of bumps and falls (before that, I used a thermos with a glass flask, which shattered into smithereens during the first fall). The design is classic, but I was attracted by this black insert - it looks great. In addition, as it turned out, thanks to this insert, the thermos is much more convenient to hold in your hand.
Having used a little, I can say that the thermos is not bad. Of course, he does not set records for keeping the temperature, but it is suitable for the needs of an ordinary person. So, for example, if fresh hot coffee is poured into it in the morning, then the temperature will remain until the evening without significant losses. I can’t say for sure, but according to my observations, only about 20 degrees of heat are lost in 10 hours. As for me, this is an excellent result for an inexpensive thermos. With cold drinks, things are even better - during the day they do not heat up at all (well, maybe just a little).
The lid is also a good cup. Most importantly, it does not heat up at all, so you can safely drink from it.
