Product review (2 stars): Trampolines for your washer!
I was disappointed in this product. Instead of helping our top-loading washer not move around on the floor, the feet actually made the problem worse. The washer shifted all around and sounded like the whole thing would shake itself apart during the spin cycle. Had a repairman in for another issue, he looked at them and said they were just acting like little trampolines for the washer. We removed them, and no more problems! Not sure why others had such success and we didn't. They've obviously helped a lot of other people.

I set them aside to leave town for awhile, and forgot to return them. Hoping I can still get at least a partial refund. It was a lot of money for something that didn't work for us.
