Query: Dissappointed in product -- good brand name but is it defective?

We ordered this product after hearing it was the best can opener available. Our daughter is very particular and recommended this item for my wife. However, it never really worked well so we never use it. Instead we just use our old opener and never tried to return this "quality" product it until the return window had expired. It does not separate the lid from the can--no matter how many times you go around the rim. Once should be enough, but it just doesn't work. At first, I would show my wife that I could do it, but now it does not work for me either. My wife is insisting I do something about it. I say throw it away and look for something better, but she thinks the brand is probably ok and that we probably got a defective opener. Geeze...I guess I will buy another one and see what happens.
