While this is a low end burr grinder it is still way better than any blade grinder. The grind is generally pretty consistent, as far as my untrained eye can tell.
Negative Product Points
(I haven't used any other burr grinders so I don't know if they all have these problems or just the Capresso) The Capresso is messy, it practically needs cleaning after every use. Depending on the size of the beans and the grind clogs can and do occur. There's no off switch so the transformer inside is constantly radiating heat which could cause your beans to age prematurely.
Since this is my first burr grinder I can't really compare it to more expensive models. However I have used different blade grinders and they all universally blow compared to any burr grinder. I only use this to make French Press, Moka Pot, and the occasional pseudo Turkish coffee and its always worked fine for those uses. I know CoffeeGeek has a lot of espresso junkies and unfortunetly I can't offer any advice as to whether this will meet your needs. I suspect that if you've just bought a $600-$1000 espresso machine you might want to get something higher quality than this.
