The problem with can openers today is that just like anything else, they're made in chiner. Anything made in chiner is of significantly lower quality than those items manufactured in the US, Germany, Switzerland, etc.
You may say, but I don't want to spend X amount on a can opener and opt instead for for a cheap chiner one. Well, that's fine, just expect it to break within a week, if not immediately.
This summer I bought a cheap can opener for the RV, just to use a few times a year. It broke on the first can.
I can risk the sharp can lids for one that actually functions.
