Have a 6 cups espresso maker (electric) of De Longhi and the aluminum screen sat down constantly. So I tried a stainless steel sieve of an old 6 cups stainless steel pot and the problem was solved! This set is like a spare thereto, which is indestructible. Cleaning in the dishwasher is not a problem and the gum you need eh gradually, so it all fits together. Fast delivery and as described!
