Product review (3 stars): Don't get your hopes up!
After reading many reviews, I was hopeful that this product would solve my washing machine vibration issues. Whenever I run my washing machine, it can vibrate the second floor which can be annoying. After calling the company for some information (and NOT receiving a call back), I still purchased them. They do just an okay job of reducing the vibration. I wouldn't get my hopes of of eliminating your problem. It's too bad the company doesn't respect its prospective customers enough to call back. I'm not sure the young girl answering the phones does a very good job by the way she handled the call.
