Using hard water will ruin your espresso machine. Soft water no higher than 50ppm is required to keep your espresso machine running for the long term. Using hard water will void the warranty.
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.
I saw many positive reviews of this grinder. I was hesitant to buy something NOT made in Italy, but I really wanted to try a Flat Burr grinder. After using it for a few weeks, I am quite impressed. It is a much better espresso grinder than my 15 year old Baratza.
