It's a little dirty on the outside and is about a month behind it's cleaning schedule but it still makes excellent batches of coffee. We use our Technivorm on a daily basis at the Sweet Maria's office/warehouse and abuse it, making over a thousand pots of coffee a year for our office staff and warehouse crew.
It's about six years old and has never let us down. Once in a while, we do a deep cleaning with Dezcal and use Cleancaf to get the coffee residue out of the three carafes we brew into. It's nice that it works as well as it did the day it was unboxed.
