From jet aircraft to electric car ...

... I refer to the above. Before the vibration machine (Miele W 5873 WPS Edition 111) is not hopping, but has been significant noises, just during the spin cycle and despite a straight stand on tiles (tiles on concrete floor).
After installation of the damper (the way to the one described here by "Mr. K. Red Sprite" method with the wet wipes under his feet, which works just fine, thank you again for the tip), the machine runs much quieter and above all very quiet, stands fixed without even a millimeter to move out!

Strong buy recommendation for the dampers, especially for the price with an unbeatable price / performance ratio.
I will buy again for my in-laws, whose machine is older and even louder than our previously was; o)
