I’m one of the folks who bought a DF54 a while back and have been going insane with clogging issues. I replaced parts and did all the things suggested to me but I finally caved and bought the Eureka Mignon Zero. Literally the first time using it my friend commented that he can smell the coffee which is great. I barely had it dialed in correctly but the espresso I made (with beans I regularly use) was the best tasting one I’ve had. I had to google to see if that’s even possible and yeah, apparently the burrs are an upgrade from the DF54 and can result in a more evenly extracted coffee, contributing to the better flavour. So far I’m loving this grinder, and it’s a bonus that it comes in yellow, like my Profitech Go!
