I can scarcely believe I have the same unit as others here who like it so much. This thing can hardly be called a can opener as far as my experience with it goes. I cannot get it to open a can without massive amounts of fussing, starting, stopping, repositioning. It's exhausting! The lever/switch thing on top is so large it blocks my view of the mechanism, making it that much harder to precisely position the can I am praying to open sometime before it passes its freshness date. And the lever makes a habit of getting out of position and jamming. The designers of this terrible product should be sentenced to using it. No, I take that back... it would be too cruel.
