The lever gives you just enough grip to pop lids without any strain, and it cleanly cuts through the metal edge every time. I finally threw out my old twist-style opener after using this one.

My hands aren't what they used to be, so I was worried about opening cans, but the leverage on this thing makes it easy. It grips the lid securely and there's no sharp edge left behind. Opening a big can of tomatoes took maybe ten seconds.

The lever handle does most of the work, so I barely have to squeeze at all. It cuts cleanly around the rim and leaves no sharp edges, which was my main worry with a manual opener. Cans that used to fight me now open in a few seconds.
