It may not be easy, but I gotta recommend she checks the feel and fit. If you notice, the KitchenAid has a nice big rubber button and a shape which should be easy for her hand. We had one, a Braun I believe, and the thing had a terrible shape and awkward button that my wife couldn't push for more than a second at a time. It took her two hands to work it. I had no problem, but she didn't like it and it "had to go."
