This gem is wonderful and so quick with opening cans.  And it's quieter than many other electric can openers I've heard over the years - they have a tendency to sound almost like a freight train is in the kitchen.  The hidden knife sharpener is a great addition, and the height of the opener is perfect! If you are dealing with arthritis in the hands/wrists, no more pain - most excellent!  Thank you, Hamilton Beach, for a well designed and easy to use product.
