Query: Do not buy this discontinued product

As a person with disabilities (have use of only one hand), I need "assistive devices." Instructions accompanying this product are completely inadequate. Even my two-handed aide was unable to operate it. Fortunately, Amazon's return policy saved the day by refunding my payment, providing a return address label, and reimbursed me for postage. No wonder Hamilton Beach discontinued its product.I went back to Amazon and purchased a "batteries-free" mechanical can opener that works perfectly with my one hand. It's called Chef'n EzSqueeze One-Handed Can Opener. And it's only $13 including shipping!
