We bought 2 units to replace our 18 old machines which weren't working any more. These are European models that are slightly taller than the 800 series made in America. While our counter was high enough for both units, one side had a wooden support that blocked the unit and we had to get a welder to make a special support for the granite counter. Both units work gray, but I will have to consult customer service for help as the second unit list it's internet connection and I haven't figured out how to restore it. Both machines work great and I give a 4.5 rating only because the one unit lost its internet connection. Each is super quiet and the red light the unit projects on the floor is the primary means I have to determine the machine is actually running.
