Product review (5 stars): Shake Rattle and Roll
I have an upright washing machine that shakes like crazy transferring the vibrations to the utility room floor and surrounding walls. I laid tile in the room to stiffen the floor but the machine would still wake the dead. With these installed the machine still shakes and makes a ruckus but it remains steadfastly in place and the surrounding structures are not affected. Great product - Does what it says. Only concern is the price seems a bit steep.
