Query: Rarely opens the cans -- and never on the first pass

I expected this to be a favorite purchase -- it was a KitchenAid product, and would keep another applicance off of my countertop. But, instead, it's one of the worst purchases I've made. If it manages to open the can at all, it will be after the can has gone around 3 or 4 times. VERY disappointing.
