for now no complaints. coffee stays warm for several hours provided to remove the container from the base to avoid the fresh air penetrates into the vacuum pot. aesthetically, I find the product rather handsome in black and white. you can adjust the coffee maker to have a more or less strong coffee. if you clean the coffee maker quickly, the coffee does not mark easily. only downside, is hard to see the lines for the determination of eau.il would have been wise to blank the different traits. in all cases, one has the money. I recommend it product.
