I was really hoping this coffee grinder would be easy to use because I don’t always want to use all my strength for a double shot of espresso. I’ve only been using it on pre ground coffee to get it to a finer espresso grind, but it’s worked great! makes great espresso even with probably mediocre beans. I actually really enjoy manually grinding them. it’s very easy to adjust and I do believe that the burr itself (the piece that actually grinds everything up? if that’s what it’s called) is porcelain, not plastic as some people had said. It’s also kinda cute in my opinion, and I really appreciate the extra jar. The size also could be great for traveling, and it’s easy enough to take apart and clean that you could use it for multiple things, such as coffee and different spices. 10/10 worth it!
