Product review (1 stars): Poor Choice for LG Machine with Base
I installed these under an LG washing machine which has an LG base with a drawer.

They are hard to install,  bordering on dangerous, since the machine is heavy and stuffed next to a dryer and wall.  It would be nice if a tool to jack up the machine were included.

I don't know how well the pads would work for an LG washer without an LG drawer base.  With the base the washer moves very wildly.  Its vibrations are much worse than without the pad.  The amount of energy put in the floor, concrete in this case, and thus into the surround walls, is less but the washer is subject to much more vibration.  Items on the top of the washer now fall off during its cycle.  This didn't happen previously.  I'm afraid that the washer is being damaged by this much greater level of vibration.  I tried putting bags on water softener salt in the drawer unit but this didn't help and overloads the drawer unit.  I'm going to remove the pads and toss them, the 30-day Amazon window for returns has past.

The physics of the situation appear to be such that a heavy washer sitting on a lighter, and not very rigid, drawer base will be subject to large vibrations.  The manufacturer should know this, and I believe Amazon should include in the listing on Amazon that the pads are not for use with LG drawer bases, or at least that large vibrations will be the result if the pads are installed.
