Beautiful design - vulnerability lid

On the plus side:

* Stylish design (the brushed aluminum variant)
* Robust - all what belongs to it makes a solid and tight impression.
* Easy to clean - screwed cup rinsed, cover briefly cleaned under warm running water, around it cleaned even with washcloth. Done.
Gebürteter aluminum cup without painting is also dishwasher safe.

On the negative side:

* Performance not quite as promised
7:45 fully replenished with fresh coffee from an espresso machine.
Previously cup of boiling water replenished so the cup inside is pretty hot to get even longer heat.
By 9:45 you should have drunk it, later it's for a good coffee enjoyment too cold.
Cup is all the time in the room at normal temperature (20-25 ° C).
On cold insulation I have not tested since it is for me a pure coffee mug 2 Go.
Drink * The patented lid for quick "out of the box" is also the weakest point in terms of ...
1. Expresses namely a moderately filled backpack something to Schlürfknopf has you quickly some of the content in his backpack.
2. The plastic / Gummmi is a good conductor of heat and cover almost reaches the temperature the filled beverage.
Thus, most of the heat is dissipated through the cover, this would be better insulated wants 1h longer the temperature are maintained.

All in all I'm satisfied, but I had expected a little more.
Price I find okay, only the insulation could have been better.
