This Geschirrspülduft is the best I know. He has kept us extremely long, about 3 months with daily washing and above all, he does not smell so artificial and intense as the low supermarket products. We had a very bad experience with those real, plates and cutlery smelled days after washing to chemical agents. Just imagine how unhealthy that's when the truck adheres to the dishes. At Miele, which is not the case. Rather invest a few euros more, but in this neat product.
