I recently received the KitchenAid Automatic Milk Frother Attachment to use with my espresso machine, and overall I am impressed. It is easy to attach and use as long as you follow the instructions step by step. It makes for some AMAZING coffee. It is like having my own coffee shop. My only complaint is the little bitty brush that comes with it to clean the hose. It is easy to use, but a bit of a pain to clean. However, the finished product makes it well worth the work. I would still recommend it to others who like fancy coffees.
