If you saw 2 Five Star Reviews and no other feed back like I did, you, like myself, probably thought it was a bogus review. I still don't know, but I do know, for now, the first time I used it, rates 5 stars. This unit came with 3 chopper blades, all parts, including grind plates and chopper blades ALL stainless steel and sturdy and hella sharp. I ground up over 60lbs of meat and about 10 lbs of chicken necks, that went through easy as a bag of Cheetos but the 20 lbs of turkey necks gave a bit of a problem. When I put a whole one through, when the large end was going through, the unit jammed. No reverse, so I just took it apart and worked that sucker out. The rest of the necks I had chopped down to more manageable sizes, (about 2-3 inch lengths,) and it worked great...loud but worked fine. The outside of the unit started getting a bit hot, (maybe 20 lbs of turkey necks? yep, probably) but it never missed a beat. I won't use turkey necks again, as chicken necks are so easy and not a risk. I ground carrots, sweet potatoes, (hard as rocks,) Kale, (I'm making dog food,) and I loved it. I ground 70 lb of combined product and it took 2 hours...but I was butchering beef hearts too, so this thing rocks! Anyway, it's got good warranties and so far it's good voodoo. Buy it.
