One touch of hands for free can opener: put it flat on, but just be sure that Cutter and equipment are lined up with an edge between them you can. Then just press the button, the electronic opening opener is automatically cut at the sides to eliminate sharp and dangerous edges.
Without sharp edges: the side system of the cutting system removes the top and leaves a Smooth edge (4 new AA batteries required, not included)
Do not require LABOUR: Ideal for people with arthritis or manual pain, not requiring manual labor or strenuous squeezing.
Lightweight and ergonomic: the size makes it comfortable to hold and easy to use, it is easy to store the opener in the drawer, it does not take up much space.
Note: 1) the cutter will not work if it is not positioned correctly on the rim can. 2) I use 4 new AA batteries. 3) Do not lift or decisively remove the opene.
