Product review (5 stars): Worth every penny
I work in industrial manufacturing and started looking at sourcing some raw sorbothane and having it bonded to feet of my high efficiency washer.  On high speed spin, my LG washer really shakes the house.  I was skeptical that these feet could make enogh of a difference to warrant their cost.  It is like night and day.  These are truly worth every penny- I hope they last, but they look to be well made and designed.  They may help quiet your noisy washer, too!
