I've followed the recommended amount, and the machine after I once thoroughly espresso machines, thermowood just cleaned with the cleaning brush fr I can also recommend this ground with the Solis 166. After that I again cleaned with the brush, and ground 24 g of one of my homemade coffee with it. Since it still very small residues of the cleaner could be seen, I did not drink the coffee grounds, but the compost bin supplied. The Grindz should indeed be harmful to health, but since I have a very strong imagination, I only prepared me from the second grinding a cup of coffee, which has then tasted my usual delicious.
The beans are then ground again quite smoothly, which is why I can recommend the Grindz for Solis 166.
