Product review (5 stars): Better than I expected.
I was impressed by the reviews of Silent Feet here on Amazon but was skeptical of the level of noise control to expect. I must say I was in for a pleasant surprise. These babies work as good as I could ever expect.

After getting them under my washer (on the first floor) I set it for a spin cycle and stepped out of the laundry room.
To give you an idea of  how surprised I was, while I was talking to my wife outside the laundry room, I thought that I had forgotten to start the spin cycle !! It was just that QUIET !  Before putting these on, I could hear and feel the machine running on the ground floor ! now its quiet as it can ever be.

The price initially seemed a bit steep to me (It is quite a bit at $40, for 4 rubber feet, u know what I mean? )  but if you care for the quiet and hate laundry machine vibrating your whole house, I think its worth those $40 bucks.

I am very happy with the quality and effectiveness so far.
