The Safe Sense feature works as advertised: when your skin touches the shredder near the blades, the unit immediately stops operating.

This shredder also has the safe sense feature just like the 460i and that prevents children from putting fingers in the opening

Another nice feature is the "safe sense" technology, which will stop the shredder if it senses a hand near the opening

The shredding action is smooth once the shredder senses the size of the item to be shredded.
