Score: 82/100Rankings

The Fullstar All-in-1 Vegetable Chopper and Mandoline combines up to eight stainless-steel blades, an adjustable thickness dial, and a bonus handheld spiralizer for extensive prep versatility.

The BLACK+DECKER Easy Assembly 8-Cup Food Processor offers a 450 W motor, three speed settings, and a reversible slice/shred disc, delivering solid performance for everyday chopping, slicing and shredding.
