DF64 II Single Dosing Coffee Grinder (Black)

Great coffee grinder. I have been using it for over a year now as of this review.Very easy to use. Has a nice adjustment dial that is very easy to work with and is also nice and easy to read.The grinder is fast and leave virtually no retention. I do spray my beans lightly with mist before putting them in, but I do not believe this is necessary.The billows on top is great for ensuring that you get all of the grounds out and it keeps the grinder clean too!

I bought my DF64 2 months ago. I came from a Baratza Encore ESP (which is perhaps the best $200 grinder) and this is a huge leap forward for my coffee. First of all, with the same beans I have developed new flavors and notes thanks to this grinder. Second, the noise. I don't know where people reads that this is the most noisy grinder ever because I use it everyday twice a day and it is more quiet than the ESP; and this leads me to the third reason: the grinding time. I drastically reduced the grinding time for my beans. I can grind 18 grams of coffee in a third of the time I could with the ESP, so: less time + less noise = more comfortable grinding. And last, the dial. It's very precise and I can dial my espresso and pour overs with accuracy, adding or taking off seconds of extraction with very little adjustments. Overall, a great grinder that payed off really quickly. Also the looks! The quality construction is beatiful.Noblesse oblige: this is not a rant against the ESP, which is a great grinder and has given me excellent coffee (espresso and filtered), but this is really a good upgrade if you have the money.

I purchased the DF64 Gen II from MiiCoffee and received the order promptly. However, upon opening the package, I discovered that the (Metal Collar) accessory was missing. This is a simple and easily replaceable part, but I'm unable to find a direct way to contact the seller within the order or on Amazon site.I've tried searching for contact information on the product page, in the order details, and even on the seller's profile, but I haven't been successful. Amazon has suggested that I return the entire unit, which is a significant inconvenience due to the weight, cost of shipping, and time involved. It's frustrating that such a minor issue requires so much effort to resolve.I've attached a photo from the Manuel showing the included accessories of the DF64 Gen II . I have two of the three accessories, I am missing a very small part (Metal Collar) easily shippable item UPS, Amazon and or USPS.While the product itself seems to be of good quality, the lack of accessible customer service has me concerned.9/30/24 UpdateI’ve been using the DF64 Gen II grinder for just about three weeks. I am very pleased with the grinder and its performance to this point. The only issue I have is a personal preference issue, as the indicated dial “Pointer” inadvertently covers up some of the numerical values making it difficult to locate your precise numerical position when it’s in a certain positions.One solution would be to change the color for the indicator lines representing 5,10,15,20 etc. or make them longer.The dosing cup and rubber grommet provided all works very well.Once communication was made with MiiCoffie their responses were prompt. After communication back-and-forth, they understood the confusion within their documentation and resolve the issue with the missing metal collar. They also mentioned they are going to update their documentation to avoid this confusion.

The MiiCoffee DF-64 replaced a 8 year old Baratza Forte (following its untimely demise).My first use impression was WoW! but that has tempered a bit after a couple of weeks use.The grind (for espresso) is quite fine with very narrow particle size distribution. When the ground coffee hits a water film it spreads outward quite quickly and evenly.The static discharge control works in unexpectedly. The collected grinds are incredibly fluffy. If the collection cup is mounted in that fork on the exterior, a bit of a mess is created. Not as bad as with the original DF-64, but still messy. So, I've taken to holding the collection cup right up against the discharge chute, but it can overflow. I may resort to stopping halfway, tapping it to compact the powder a bit, and then resume grinding to finish the dose.The grinder is billed as very low retention, but after making two espressos, using the bellows (which makes an airborne mess again), there is retention (left image). A quick vacuum cleaning (just a few seconds) does clean the grind chamber (right image).The grinds, when transferred to the portafilter cup (a 20g VST) form a clump that absolutely requires WDT distribution, a step never needed with the Baratza. The clump feels somewhat warm to the touch, so perhaps I should open the burrs a bit.The coffee is generally wonderful, but it appears that electrostatic induced retention leads to variation in extraction and flow from the first cup to the second - the first cup showing higher extraction @1.2 0 1.3 g/s, while the second cup frequently seems to be brewed from less coffee @1.5 - 1.7g/s. Again, the quality of the espresso is quite good tasting and full-bodied.Since this grinder cost a small fraction of the Baratza Forte, I'm not disappointed and I may have a few things to learn.

Heavy but a great grinder. You do have to adjust the settings everytime you switch brands of coffee but it’s easy and feels like a quality machine.

Clogged up after two uses, put it right back in the box and returned.
