Cold drinks are warmed up after 4 hours from refrigerator temperature to slightly below room temperature. So you're still cool, but not really cold, when the starting temperature is 5 degrees.
Hot drinks decreased from nearly 90 degrees to about 50 degrees in two hours from.
It's still warm, but nevertheless a significant temperature loss which is also noticeable, if you touch the cup: it is really hot, almost too hot to touch.
But in spite of the temperature loss or heating within the times: The drinks are still rather hot or rather cold, just the way it should be. And frankly, I need rarely two hours to drink a cup of coffee or a glass of cold tea.
The technology of the cup is good, you can actually drink from all positions it, it drips nothing and he holds tight.
And looks good.
It is very positive that you can build it almost completely apart and can even be cleaned in the dishwasher. Very easy to clean.
Unfortunately, the inner workings of black and the cover is pretty heavy, so that a white filling line would have been really helpful. Without these, it is estimated before the filling wrong and when screwing it runs then.
Sure, you learn over time, but a small, clearly visible line would have already helped me with the first filling.
Overall, however, may keep a good thermal mug which extends only not quite reach the promised time, or the temperature is not quite as good as you might think at the promised time.
