I have been using a can opener that it batter powered and we change batteries every four months. I got tired of that routine and decided to buy a nice one. I visited Wayfair.com online and found exactly what I wanted. It was inexpensive but works like a charm. I love the knife sharpener too. It's quick and now I am a happy can opener owner. Most people feel that a can opener is very common and not worth buying. Let me tell you about those people who could not afford to buy a can opener. Isn't it funny that when you don't have something for many years that even a can opener is something to brag about. "Reality? what a concept".
