Product review (5 stars): Excellent product, absorbs the shaking quite well.
Excellent product. The washer still vibrates, but at a smaller range. It used to vibrate/shake excessively at all speeds above LOW. And if you put in more than two pairs of jeans, the washer would walk a few inches and bang into the dryer.
After trying to level it, then laser levelling it, then taking it off the pedastals (to lower it's Center of Gravity), nothing really helped the situation.
After reading the reviews from this site and from multiple other sites, I ordered the product. I installed these feet in two minutes and ran a load of towels on MAX rinse/spin level and it worked great. Like I said, it vibrates still, but it no longer shakes the neighborhood and no longer sounds like a box of screws broke open inside the washer (and yes, I removed all the shipping bolts and other "ways to help" that many other people mentioned).
It is much quieter and tolerable than before the feet. The washer stays put and the feet absorb the shaking quite well.
