Product review (5 stars): Great product!
I have been debating to purchase these after our brand new LG WM2103H "True Balance" washing machine started to "take off" on heavier loads.  Overall, this product has decreased the noise level.

The WM is located on the 2nd floor of a newly constructed ICF house (cement) on top of a pedestal. I was told this model was made for 2nd floors in mind.  Well, it's not. I would never buy LG again.  Of course this is not a review for LG, but if your looking to purchase one for your 2nd floor, research other companies.

With the pads, the machine now has more of a "wobble" effect with the pedestal, but amazingly it keeps the machine grounded, reducing the loud "take off" noise. I am just concerned about long-term affects on the WM and the pedestal. In the end, I am going to have to put the WM directly on the floor, which defeats the purpose of an easy-loading WM.

In conclussion, I would recomment the purchase of this product, but of course there are limitations. I have to give it 5 stars because it does what it says, however, depending on your machine, it may not be what you expect. You can only do so much to the "stuff" that LG is making.
