Fastest delivery ever 9 h. And installed because another review as follows. Share the mat 10 mm thick, in thought in 9 fields, cut in each case the outer middle squares of slightly smaller. That's left looks with a little imagination like an "X". Put this x in the place where the machine is to stand. Put on the corners a (very thick) tile eg 15x 15 cm and place it the previously cut squares. Then they put sooo carefully the washing machine. From there is definitely quiet. Herrlich. The mat Rubber smell paid - no more than a bicycle inner tube. :-)
