When this knife first arrived, it was great. It cut great and I couldn't have been happier with it. Then, within a week or two, it began to stop cutting even though the motor still was running. Sort of like it locked up when it had to cut through something more than a simple loaf of bread. I was very unhappy and sent it back. Did not reorder so I don't know if it was just a one item problem or something general with these knives.
