Query: Crank very hard to turn

The crank on our old grocery store can opener is easy for me to turn but difficult for my physically impaired wife so, because of the nice reviews, I ordered this one hoping she would be able to use it. It turns out that the crank is so hard to turn, at least on the one we received, that I don't even want to use it so I went back to our grocery store opener. I would return it had I not lost all the paperwork.My wife's name is shown as writing my reviews because we both use the same email address. I don't know how to set up my own email account.
