I bought my Kenmore HE2T Washer and dryer set about three years ago because it had a nice suspension system in it that was supposed to be OK for 2nd floor laundry rooms. Well, it didn't work. This machine shook everything.
I did some research years ago on this site and someone recommended KE Shake Away Pads. They barely worked. It helped so i just lived with it assuming there was no better fix.
Recently, I came back this site to see if anyone else had any ideas. I ran into a post where they were talking about Silent Feet. WOW. These pads are amazing. 95% of all shaking and vibration is all gone. Get these. Don't just take my work. Read the reviews. I bought them on Amazon.com. Best $40 I've spent
