Product review (5 stars): Exceeded my expectations
We have an older top-load washer that danced across the laundry room floor. The vibration was so bad that we couldn't watch TV or even take phone calls inside the house when the washer was running. We put the mat down today, leveled the washer, and threw a load in. Not only did the washer not dance, even an inch, but we were barely even aware of the spin cycle.
