With my previous grinder I'd been having a hard time dialing in my dose on my Breville Infuser without having to use a dual wall filter. But as soon as I put the DF54 to work, my troubles were over. I've been able to dial in the perfect shot with multiple different beans.
I just want to say off the start you guys are amazing my first order came damaged you guys responded to my email and pictures the very next day and had a new one being sent out to me which arrived today July 23 and was as far as I'm concerned and pristine condition excellent condition there is no damage whatsoever I could see with this one and it looks amazing and works better than I honestly expected for my first e61 style heat exchange machine.
Its a great value for a grinder, and one that might be in the top tier as a travel grinder. The one easily correctable issue is the pint glass looking cup that comes with it. It really needs to be paired with a true dosing cup, but to do that you need a "highchair" for the dosing cup. If you have a 3D printer I've got one loaded on printables at https://www.printables.com/model/1363325-turin-dm47-coffee-grinder-highchair-shaker-stand that should fit a few (one linked for $11.xx that works well) dosing cups.
Accurate. Reliable. Perfect. I love it. Highly recommend it.
