This is the BEST can opener! I bought one a few years ago as my beginning arthritic wrists would ache just opening one can with a manual opener. I cook a lot with a variety of canned goods. No stress on wrists! Plus, no danger of cutting yourself. My little grandson can safely use it. Perfect for replacing lid if using only a portion, like catfood. I bought another for 2nd home and one for elderly friend. It's my favorite appliance!
