1. A thermo mug for warmth. Because that does this much better than a coffee cup.
2. The attached bene capacity is only achieved if you fill the cup to the brim. Then you can but not replace the cover. Or the drink pressed or injected through the drinking spout. Ie In fact, he holds little more than a normal coffee mug (not mugs!).
3. Car Mount: In my car "floats" the cup in the holder. To stand firm, he does not in any event that prevents its conical shape.
4. Dishwasher he is not. But even if you washed it by hand, running water between the actual cup and the colored cover.
The lid closes tightly enough to prevent sloshing out of the drink, eg in a sudden stop. What is useless to me, because, unfortunately, does not fly the complete cup from the holder and then the lid "right" is tight, I have the coffee oa still in the car.
The only positive thing about this cup: It does not smell like plastic and does not taste it. But that is too little to have to get another point. I disposed of him - pity.
