Speed: This model performed good in our speed test which was based on the amount of bone that was ground in one minute of operation.

Fineness: This model performed worst in our fineness test which is based on the fineness of grinding beef bones and vegetable scraps.

Noise: This model performed worse in our noise test which is based on a combination of decibel readings while grinding bones and other table scraps.

The Project Source (Lowe's) PSD-125 is part of the Garbage Disposals test program at Consumer Reports. In our lab tests, Garbage Disposals models like the PSD-125 are rated on multiple criteria, such as those listed below.

Speed: A high score means faster grinding of food waste. Top-scoring models quickly break down tough scraps like bones and vegetables for disposal.

Fineness: A high score means finer grinding, reducing food waste into smaller particles for smoother disposal. Top-scoring models help prevent clogs and improve drainage.

Noise: A high score means quieter operation while grinding food waste. Top-scoring models produce less noise, making disposal more pleasant.
