First off, let me start by saying Espresso Outlet's customer service is top notch! My first order arrived, and the grinder stopped working on day 5. I contacted EO and they immediately arranged for me to return it (still had the box) and then shipped me out a new grinder as soon as they got confirmation of it being shipped. A+ Got the new grinder and it's been smooth sailing since. Also, I think the first grinder I received must have been the last from a slightly older lot, because the new one had some very slight differences, like the chute you feed beans into was detachable on the first one, but not on the second.
But on to the grinder review. I upgraded from a Baratza Sette 270wi, and let me just say, there is no comparison. I have the stock espresso burrs on the DF83V, but man are they great. Maybe someday I'll look at fiddling with burrs, but for now I'm really enjoying these. There is so much more nuance to the coffee flavor, it's like I'm discovering great home espresso all over again. This thing is a beast, too. Heavy, feels rock solid, and QUIET. My husband doesn't share my love of coffee. He has always complained about the noise my grinders make in the morning. Two days after using this one, he tells me "I like your new grinder." Me: "You do? Why?" Him: "It's quiet. I can sleep through it in the morning." So take that for what you will.
I also had the chance to use a CF64V prior to this one (a friend's), and while that one also had great clarity and nuance of flavor, clean up with the DF83V is world's easier. I would absolutely recommend this grinder. I think it very likely compares favorably with much more expensive grinders in its grinder class.
