Product review (1 stars): Made things worse!
We have our washer/dryer on our 2nd story and bought these thinking that it would reduce the noise/vibration of doing laundry while the kids are sleeping.  Unfortunately, we noticed INCREASED vibration after using this product.  A big disappointment, especially for the price we paid.  Needless to say, the feet are removed from the washer - we couldn't return them as there were scuff marks from the bottom of the washer on them.  Guess we're just out of luck!
