Now the washer stays in place. Did exactly as advertised, my noisy and rocking washer is now much quieter.

The washer vibrates right off and broke the product. These vibration are not sturdy. A pain to install and increased both vibration and sound.

These discs are perfect. They are harder than rubber or silicone so they don't squish down.

These are not 320mm in diameter. If you read the small print it says that but the title says 320mm. Better read all the fine print.
