Bests & Worsts Reviews from Amazon

I don't know if this will help anyone else, but be very careful if you are purchasing this as a replacement for the K5SS. My mixer is about 14 years old, and I needed a new beater. After researching what fits, this was the item according to the Kitchen Aid website. It looks exactly the same on the outside, but something is not right on the inside. It will not lock into place when you put it on. This came in an original looking Kitchen Aid box, and all looked great on the outside, it just didn't work. I will be calling KitchenAid to get advice and will update if I learn anything of use. Service in receiving and refunding was prompt by Amazon.
