Product review (5 stars): Anti-vibration pads
In use now for roughly 30 days. Never used front loader without pads, so nothing to compare to (before / after).  Using on LG direct drive true balance. Construction is 16" o.c. 2x8, 3/4 diagonal with 3/4 inch plywood on top over crawl space. Finished with cork floor. The machine spins fast at maximum. 0 vibration in floor and walls. Anti-vibration feet feel like they are taking a grunts load of force when you touch them, but nothing in the floor immediately around the pads. So far I say worthy investment. Don't skimp on the set for the dryer to match height. Tough expense for ascetics, but 1inch difference would be unsightly.  Can barely see the feet when standing up.  Went with blue because they were $5 less per pair when purchased. Looks fine with graphite machines. The blue is only at the bottom of the pad. The rest is black. Delivery crew installed when delivering the machines, but could be a difficult task for a one person job.
