Product review (5 stars): Works unbelievably well.
My 7 year old Bosch front-loading washer has shaken the whole house on the spin cycle since day one, but recently my wife has been loudly complaining so I googled the issue and found that many people recommended this product as a way to dampen the vibrations. I thought they might help a little bit, but was pleasantly surprised that they all but eliminate the noise and house shaking that was going on - I wish I had found out about these years before.
