They include long-term testing notes, and they also ask several experts about their favorite openers.

After testing 11 smooth-edge can openers, Maryellen Driscoll finds one clear favorite and three runners-up. She writes a few sentences describing the pros and cons of these four; she names the losers, but she doesn't describe them. Driscoll finds she prefers smooth-edge can openers with their knobs on the side (like a regular can opener), and built-in pincers to remove the lid aren't necessary. Although this is an older test, three of the top four picks are still current.

The EZ-DUZ-IT works exactly like the old Swing-A-Way, even flawlessly opening a can in midair (i.e., without supporting the can on a table).
