I have had this coffee makers for two years now and it still looks new and still makes great coffee.  I am so pleased with this.  This is my first Braun maker and it is perfect.  I always make 10 cups and the brew is perfect every time.  I do not use any chemicals on it when I clean it, I just wipe it down with a damp paper towel everyday and it looks just like it did when I pulled it out of the box. I change the water filter regularly and run the vinegar through on schedule.  I love it so much I bought a spare.
