Product review (5 stars): Absolutely Exceptional Service from KitchenAid Company...
This item is not universal, it will not fit every Kitchenaid Blender, I just had a similar experience with the clutch coupling overheating and melting off. Ive had my blender for a little over a year,  I called the factory number on the bottom of my blender and explained my situation,  they asked me gor my lender's model and seris l number they were able to actually match the information that I provided with their data regarding the year the blender was purchased. They told me that my  factory warranty had run out, but because the item had literally overheated and melted off they company decided to send me a brand new replacement blender at mo codt to me...I was told to just put my blender in the box that the new blender came in place the return label on the box and take it to my FedEx office to ship back...I have always couched for Kitchenaid products...now I can vouch for the quality and service of their company...exceptional service!!!
