The Columbia is a feast for the eyes, it looks really classy and the form is super successful. The function of the coffee maker is awesome coffee pure, brewed up water, sieve high, wait a bit and press sieve down, is ready. And the freshly brewed coffee tastes way better than in any simple coffee. I was indeed the double important to keep it hot for long. And here I have to make concessions, because for a long time he does not keep unfortunately the heat. I sum up the coffee maker on the outside he is mighty hot words, so that he does produce a lot of heat on the stainless steel. Drink an hour later still hot coffee is definitely nothing, since it is no more than lukewarm. Keep twisting the cap to the heat, as well as helps only slightly. This sits well not quite suitable for disabled, wobbles a bit back and forth. What I would like to mention positive, it is washable and super spotless abtrockenbar. I'd get them for a bargain price (60) and it is worth in any case.
