Product review (5 stars): Worth it
I purchased a new washer and it vibrated like crazy.  I called and did troubleshooting with Samsung and nothing worked so the sent out a repair man who said nothing was wrong with it.....even though my washer was loud, banging, shaking, vibrating, knocking, took an hour to wash a 23 minute wash, and made my clothes smell like mildew.  I thought for sure I was going to have to buy a new washer but decided to try these.  It is my first night of using them and so far so good. It has improved about 95% and I'm very pleased
