Query: Innovative E-Z way to open cans in an instant

It's true - fixes on the top of the can, turns very very gently and easily, then the entire lid of the can is off. (It doesn't hang on). So you don't have that classic (and ragged and sharp) swinging lid to fold down to save half the can in the fridge. But, it's amazingly light and fast to do its job. Neither the lid nor the can rim is sharp.
