My husband and I have had several can openers that will not open some cans. This can opener has opened every can on the first try. It's quiet too. We do have to keep one hand on the can opener if we open a heavy can...it falls forward if we don't keep one hand on it. We don't mind that. We are happy to find a can opener that actually opens cans.   

Pros: Opens all sorts of cans, great price, quiet to use, push button will take cutter of for easy cleaning
Cons: It will tip forward if a heavy can is on it. Solution is to put one hand on the top of can opener.
