I have been using electric can openers for 30 years. The real downside of most of the models is the way the cutter enters the top of the can, potentially contaminating the liquid/food inside. Does it ever come clean enough? I never thought so. Here is an ingenious little device that cuts around the rim, doesn't touch the food (that I am aware of ) and slices a nice, neat little top that you can also use to store the food if you don't use a whole can! It is also effortless to place a can on this can opener. Just make sure the cutter is lifted (from U-loop in back), put the can up next to it, and good to go. The can opener grabs the can without your having to adjust it - or like other can openers having to keep trying to plunge the cutter into the can before it will begin its rotation. I LOVE this can opener and will buy another one when this one quits. Another important fact: You will never cut your hand on the sharp edges of a can top ever again. The smooth under the lip cut by this can opener is a lot safer to use. Recommended highly. Durability I've had it for five months, so not a very long test of durability. So far, so good. Design Safer, easier to use, and provides a way to use the can to store unused product.
