Product review (1 stars): Made it worse, sent back
I had a slight wobble in my washing machine. Tried the feet adjustments. Tried it on and off the pedestal. Nothing really seemed to fix it. I tried these after reading so much about them. What a mess! Both with and without the pedestal, this was worse. Tried them between the washer and the pedestal and then the pedestal and the floor. Went from a slight vibration to a full on chatter and bounce! Maybe it's my tile floor or whatever, but after putting the machine back on the pedestal without these, the slight shake returned. I can live with that.
