This item is very small. The description says that it's "1 cup" but that is misleading. It's certainly not 1 cup of liquid that it produces. And it's not for a coffee cup size drink. The bottom part that you fill up with water would hold about a half cup of water--at the most. And the espresso part holds about two tablespoons of espresso. It's tiny! I used to work at a coffee shop, and we used more espresso to make one small espresso drink. One shot of espresso would require double the amount of espresso that this maker can hold. So even if you did use this product to make yourself a shot of espresso, it would be a very weak one because it doesn't hold enough espresso to make a normal espresso shot.
I can't imagine how you would ever use this espresso maker. I guess it might be good for a dollhouse....
