Great grinder. Quality materials. Solid metal construction. Excellent grind range from filter to espresso brewing. Simple operation. No issues with coffee getting jammed as I read in some comments. Grams of coffee you put in is what you get out. Very good grinder for the price. 100% recommend.
I was lucky enough to snag a batch 2 DF54 and I got it about a month after ordering. This thing really makes good espresso possible. I was using a Timemore C3 before and couldn't get a good shot. This really changes the game. The burrs came perfectly aligned. The stepless adjustment is great. I wish this grinder hadn't tried to be a filter grinder too, because the range for espresso isn't huge. Stepless helps a lot though in that regard. No mechanical issues. Very solid grinder with good build quality that should last for years to come. This is a necessity if you are on a budget but still want to make espresso, it's the best grinder in the price range.
It’s built solid and grinds very good.
I replaced an Expobar with a PID that was getting old. This is a nice replacement. The shot counter and pressure gauge on the group are nice additions. I wish the drip tray was a bit bigger and the reboot could switch between C and F readings but those are minor points. I love the machine. Great customer support too.
While the DF54 is an improvement over the grinder I had before, I have been disappointed with the inconsistency, especially after any adjustment.
