Only at first glance, ....

At first glance, I was very pleased. Properly processed, works a lot better than the cheap aluminum maker and looks better because it does not start.
Unfortunately, the capacity is slightly lower, but you can live with.
After a few weeks then the disappointment - the coffee tastes bad to worse - why? The thorough investigation shows the inside of the pot is a kind of inward rolled-back "pouring edge". This should be cleaned with any tool known to me and after a while a lot of black muck is deposited then on. Since I have no desire to me every two three months to buy a new pot because the old is dirty I will probably revert to the aluminum version - which should be cleaned at least.
Conclusion: Unique design and construction errors, a pity because the idea is great!
