The coffee is initially been a bit too hot. Coffee is brewed, not cooked, Rowenta.
The hotplate keeps the coffee is not warm, it keeps him again hotter than he is anyway cooked.
After five minutes, the coffee is no longer fit for human consumption, a bitter taste, much stronger than initially and is, as I said, way too hot.
The drip-stop does not deliver what it promises. Mau.
The filter container can be removed. That's fine.
Substituting it again, you have to turn it slightly and he snaps a little one, so it does not rotate and you can insert and fill the coffee filter.
Works about three times, then the "locking" no longer exists and the thing wobbles so as to himself, and causes the lid no longer completely closes.
All in all, the conclusion:
Can you do so.
Is then just botch.
People go to the moon, transplant body parts and accelerate particles at the speed of light.
Rowenta makes Foehn and coffeemakers.
Maybe they should stay with foehn.
