Product review (5 stars): A MUST for Walking Washing Machines
I have an LG washing machine and it walks during the spin cycle.  It was VERY annoying to reposition the washing machine after every wash.  The vibration was loud enough to feel and hear one floor away.  That is until I purchased this Anti-Walk Silent Feet from Vibration Solution.  They work absolutely GREAT!!!!!!!!!!  My washing machine does not even move a millimeter from where is it placed no matter how unbalanced the load is.  Phenomenal.  Here are my recommendations and how I installed them by myself.

1.  I got the RED BOX of vibration pads, not the green box.
2.  I got a good mental image on where the feet of the appliance are in relationship to the outside body of the appliance.  Most of the time the feet are not visible when you look down from the top of the appliance.
3.  I positioned the washing machine to where I wanted it.
4.  I tilted the washing machine forward and dropped two of the vibration pads on the floor to where the rear feet would be when the appliance is on the floor.  I used the end of a broom to move the pads into the right position.  This is the most time consuming and tedious part of the process so be patient.
5.  I lowered the washing machine back down on the floor and tilted it backwards.
6.  I dropped the front two pads on the floor and positioned them to where the front feet would rest.
7.  Lowering the washing machine, I was done.

These pads are made out of two kinds of plastic.  The top layer (half the total thickness) is hard and this is where the feet rest.  The bottom layer is softer and does most of the absorption of the vibration.  It sticks to vinyl flooring so it helps to prevent walking but more importantly it absorbs most of the vibrations.  I touched this layer as my washing machine was in the spin cycle and I felt the tremendous amount of vibration this layer absorbed but didsn't conduct to the floor.

Now I do not hear or feel on another floor when the washing machine is on a spin cycle.  The feet are on the pricey side but what they do to eliminate the walking, they are very much a worthwhile investment..  This is a solid 5 star product
