Query: B&D Space Maker Can Opener

We like B&D; because of over-all durability and effective performance of the designed function.We replaced a previous B&D; under-counter can opener after about 20 years. It was still working, but getting sluggish and under-performing just a bit.Momma said it was time for a new one, but to make sure: "It is another Black and Decker!" Who was I to argue?
