Nice modern design. It fits perfectly in the hand. Cleans up great. And what the user will probably appreciate the most - it's tight. Which is the stumbling block of most thermos mugs, takeCups, etc. on the market. I recommend checking the tightness after screwing the lid (turn the mug downwards), because it rarely happens that the seal does not fit properly when screwing it in, but just unscrew it, check the seal, adjust it if necessary, and screw it back in. The heat loss is very small, among the best in the competition (tests on the net). From practice, it keeps the coffee hot even after 5-6 hours.
