I have 3 of these machines. All are dead. It's conceptually rubbish. And to a stellar level. If you look at it with an engineering eye, you'll immediately understand that it can't work for long. First, mechanically loaded gears are made of plastic. And this can't hold. Second, the water pump is completely unreliable. Two are dead out of 3 machines, all 3 less than 3 y.o.
