I have friends who really like the type of can opener that unseals the cans, as you describe, and they have the OXO Good Grips version. They really like it. It can work well.

However, I have to say, I have attempted to use the can opener at their home multiple times while visiting to feed their cats. I could never get it to work! My friends have normal hand strength. I'm not sure if it is my weakening hand grip, or that I just never quite got a hang of it, but I found it very difficult to use. For me, OXO's regular can opener works much better.

Take care,
Erin
