But the cup not only looks great, it also holds warm, long at least one hour. Personally that enough, because my way to work or school will not take longer than 30min.
Nevertheless, I have to deduct 2 stars:
1. Thermometers should one drink for longer than 1 hour keep warm (although good enough for me).
2. Very dense not holding the cup unfortunately. If you carry it upright, running from nothing. But I do not advise to carry the cup in a pocket or backpack, since it runs out otherwise.
In all, a beautiful thermal mug that does the job if you want to use it only on the way to work / school and simply carries it in his hand.
