Product review (5 stars): Works well, hidden benefit in the bottom of the pads.
OK, my house is poorly built. I was feeling the vibration from my new Samsung dryer through the floor in neighboring bedroom. Obviously, it was noisy and made it unpleasant to dry laundry while I tried to sleep. These feet seem to have solved the problem.

One nice element: the back feet on this model slide easily. They have a felt padding on the bottom. The ones on the front, however, are very sticky. That helps keep the dryer from moving. So, if I want to slide the dryer out, all I have to do is tip it back a bit onto the rear feet/pads. It moves easily.

I'm now going to get a set for the washer. That's a lot heavier, so it will be interesting to see how this works.
