The thermo cup is completely sealed in both hot and cold drinks. It has a 360 ° drink opening with Quick-Press drink closure, which I have seen in similar form in thermoses. It can disassemble, clean very well and, like all other parts dishwasher safe. However, I must point out to the fact that the thermo mug smells of coffee, since I transported the first coffee in it and the smell keeps iron in spite of cleaning in the dishwasher. So I'm going to have to buy a separate thermo cup for my tea to mix any flavors.
What also somewhat disappointed me, are the thermal characteristics - despite double walls of the content remains than 2 hours hot. I fill the preheated cup full of boiling water, the temperature after 30 minutes just yet 72 ° C, after one hour 60 ° C and after one and three quarter hours to only 50 ° C. Accordingly cooler the content when I fill the cup only halfway. So, my cup of coffee at work, about 30 minutes after I'm running directly into the preheated thermo cup, not really hot, but still very warm. After one hour, the coffee is cooled so that I no longer want him to drink.
The cup is absolutely tight and extremely easy to clean. Regarding odors and holding properties is room for improvement. On the plus side is definitely the 5-year warranty Emsa.
