I wish I would have read Amazon reviews before purchasing the Hamilton Beach 76606ZA! It worked for a while, but it fails to open cans. Even worse, as soon as the can starts turning the can opener shaves very thin metal strips from the can. Some stick to the can, some get in the food. Amazing how many people have experienced this and they kept selling it. As for warranty, you pay shipping both ways, so cheaper to go buy a can opener from a company that cares about their customer safety and satisfaction.
