This operation of this can opener is very smooth and quiet. I like the strong magnet that holds on to the lid tightly so it does not fall back into the can. I cook large meals so the height is important to me to allow me to open family size cans with no hassle. My only concern is that some of the materials used in making the can opener are light weight, in particular the lever on top that is used to puncture the can with the blade. While I cannot actually judge its strength yet, I am a little concerned that as the blade becomes dull over time the lever may not hold up to the stress.
