Product review (2 stars): Silent Feet for Bosch Vision 500 Series Washer
I own a Bosch Vision 500 Series washer and experienced mixed results when using Silent Feet.  The maker of Silent Feet, Vibration Solution, indicates that their product can reduce vibration up to 94.7%.  I would agree with the manufacturer that vibration was reduced at lower spin cycles of the Bosch Vision 500 Series washer but my experience with the product at high spin cycles is that product provides no benefit.  Floor vibrations were the same at washer high spin cycles with or without the Silent Feet.
