I previously owned a Pampered Chef smooth edge can opener so I knew how to use one. However, the old one was hard to turn, especially with my tendonitis. This one is so easy to turn and does a great job cutting smoothly. You do have to learn how to attach it to the can, but once learned, it is easy to do. I love the smooth edge because I don't have to worry about cutting myself on the lid or top edge of the can which I sometimes did with regular can openers.
