Product review (5 stars): Whirlpool 8541503 Duet and Epic Stack Kit
This is exactly what we needed!! Our stackable washer and dryer rocked all over the place to the point where the dryer would slip a bit off the edge of the washer. Very dangerous! We bought a set of the anti vibe feet and the Whirlpool stack kit and could not be happier! The crazy shaking mess has been reduced to an almost completely unnoticeable and inaudible vibration. The best solution out there! Thanks!!
