Mir is the thermo has not fallen down and that is why I am surprised that has a very Emsa product such poor Eigent companies.
In the product description is even explicitly both parts Spülmaschinengeignet are:
"High-quality, vacuum-insulated EDS body - dishwasher safe"
"Cover dismantled for easy cleaning - dishwasher safe"
On November 5th, 2014 this cup was me shipping and I use him about since.
For this deception as long as there is only one star to be something, not just for me, changes in the product.
Sorry but that's no EMSA EMSA Qualtät & does not match your house standards!
About the technology:
Wonderfully, the cup holds a long warm, even hot, which of course depends on the number of openings.
The opening itself is a bit unhygienic because you can open it only with your finger. On the area of contact with the finger, a short time later, the beverage flows past it. For beverages that are hot enough, no problem, otherwise it could lead to problems purely theoretical.
