I have been using this grinder for my espresso and it does a great job! In fact I don't even have the setting all the way to the right (espresso setting) I have it set a few notches in and it creates a nice fine sand consistency.
I was on the lookout for a great espresso machine for about 6 months but I never purchased one because I didn't want to spend hundreds of dollars. When this machine went on sale I grabbed it! I read through hundreds of reviews. (Amazon.com) has tons to read through. My only problem is that I can't stop drinking them! Both espresso and frother work great!
These peelers are VERY sharp. The even come with a cover to protect them. Maybe the previous reviewer never put the cover back? They do have a good warranty :)
