This product replaced a 15 yrs old one that died. It is significantly quieter and there is less vibration when it is running. It does take a bit longer to grind citrus rinds. But, I am pleased!
My husband reports it was not too difficult to replace, using the drain ring left in place from the older model, since that is standard across the line. But getting the plastic guard piece out of the dishwasher line was difficult. He had to dig it out piece by piece.
