Product review (5 stars): Buy one for you and your BFF!
Buy one for you and your BFF!

Save a plumber bill by using this handy little tool.

Tip #1: Just watch your knuckles-the bottom edges of a disposal can be sharp if you touch it as you perform the magical cranking action to unlock your disposal.

Tip #2: Never put mounds of egg shells, onion, carrot, potato or eggplant skins down a disposal and expect anything good to come of it.  Trust me on this, people.  Just don't do it.

Tip #3:  Remember your BFF... :-)
