I am from Europe , Miele appliances have been the only appliances in my home as far as I can remember and so in my mother’s home before me !One month ago I replaced my washing machine after 18 years of implacable performance and not one repair with the new and amazing W1 washing machine.I have been using Persil( made in Germany ) for many years but I decided to try Miele powder detergent for a change .Miele detergents are made specifically for Miele washing machines and I now know why .The results are unparalleled and surpass Persil performances .For one Miele detergent doesn’t sudd as much and rinse much better than Persil . Second it’s more economical and better for the environment because you use less .Miele detergent leaves all my white dazzling bright , without any residue and with lovely fresh clean scent .I only got the Ultra White but I will order the one for color soon .And I forgot to mention the little measuring cup which comes in the package for precise measuring !Miele you are the best !
