My husband bought this for me for Christmas less than a month ago. I used it once to grind pork and it worked great. I tried to use it again to grind beef a few days later and the metal shaft twisted apart. Didn’t even get 2 uses out of it. I won’t be spending money on a new part as I’m sure they’re defective. Also never again will I buy any kitchenaid attachments.  Money wasted
