Product review (5 stars): Great noise reducer
We bought these for our LG ventless washer-dryer.  They worked wonders.  Our unit wasn't extremely loud, except on the spin cycle.  It vibrated like crazy and sound bounced off the walls, the floors and made our apartment shake.  These anti-vibration feet really helped.  They didn't completely eliminate the noise or vibration, but unless I'm in the same room as the unit, I don't really hear it much.  I highly recommend this product.
