content: This device does open cans but it is difficult to position to get it started. It was purchased to replace a 25 year old opener that was easy to use one handed and required no strength to make it work. This one requires that you are able to push hard with your thumb (which I cannot do due to joint problems) in order to operate. If you ave 2 good hands it is fine. I need something else. Keeping this and my husband uses it.
