My annual family reunion was last week. For the first time I was able to open those huge #10 cans of beans, both baked beans and green beans without my manual can opener. This saved me lots of time and didn't scrape my knuckles like I used to. 
This can opener zipped through those 4 big cans of beans without strain. Next I used it to open the cans of pumpkin puree and condensed milk for the pies. 
This was such a great time and effort saver for me. I love it. [This review was collected as part of a promotion.]
