I purchased a 14 cup Cuisinart push button model (DLC -2014NC) at Caynes, and have used it for about 2 years, lightly once or twice a day. The buttons have cracked, and Cayne's has replaced it three times due to this. They are denying anyone else has had this problem, but I am not overly using it. Is it because I purchased it at a discount store as opposed to a high end store? Has anyone had this happen?
