The Kitchen Aid automatic milk frother is a great addition to have with the Kitchen Aid Semi-Autimatic espresso machine. The attachment clicks right into the machine and makes frothing milk a simple task.  The directions were a little confusing and I did have a bit of a learning curve to get it adjusted to my liking.  I love that the milk compartment can easily be put back in the fridge so I don't have to fill it everytime I wanted to make a cappuccino. I use the front of the frother to store my items for the machine which makes everything right where it is easy to access. The milk tube is easy to clean and I always have it ready to go.
