Product review (3 stars): Good but not great - read full review
These definitely helped with limiting the movement of my Samsung front loading washer on my smooth concrete floor, but did not completely eliminate the movement. The gel insert pads they provide are useless, don't even bother with them. To completely eliminate movement, I had to apply a dab of construction adhesive to the bottom of the pads to secure them to the floor. Now there is no movement and the pads seem to help with eliminating some vibration throughout the house. I would buy these again. Maybe they would work better on a surface like linoleum or wood floors, but not great on polished concrete floors.
