Input:
I received this knife as a gift and was quite happy with its performance, for about fourteen months. Then it began to smell funny when I sliced anything at all resistant, such as bagels. This happened several times, over the next month, before the knife simply stopped working at all. This knife was refurbished, which I hadn't realized meant the warranty was for only 3 months. Cuisinart offered to replace it for $50, which is about the price of two knives if I replace it with another brand, which is what I intend to do. I had thought Cuisinart was the top brand but obviouly I was mistaken. We've had several electric knives, made by other companies, and this one gets the prize for having the shortest life. I wish I'd read the reviews posted by other customers, who had similar problems, before asking for this particular electric knife.
