Product review (5 stars): These are the SHOW!!!
These work great. I put them on my new front loader washer which was "walking" when the high speed spin cycle would come on. This stopped the "walking" completely. They work exactly as advertised and are worth the money. I was a little worried that the washer would look a little funny sitting up higher than the dryer, but it only sits up an inch or so and is almost unnoticeable.
