It seemed to work fine for me. It tells you by whining a little as it works, but any machine would.
So I feed it conservatively, just let it chew, and don't push too much in.
I watched Disco's video's and how he uses his KA.
They are not cheap. So I don't want to break Mama's tool. But when she was making Christmas Cookies, she brought up the idea of grinding meat with it.
It gets slightly warm, or did for the grinding I've done with it so far.
Would a "real" grinder be better? Yes. And you wouldn't worry about bustin the wife's KA.
But for me, for my 2 pound batches, I think it is a good way to go.
I spent $85.38 for my Stainless Steel grinder attachment. And the mixer itself has a good paddle for mixing the meats and seasoning/cure all together. We got the accessory paddle that scrapes the bowl. I DO NOT use that! I use the aluminum standard paddle so I don't contaminate her cookie tools.
But for me, using the KA eliminates buying a grinder and a meat mixer. Incidentally, I ran across a video of a guy using a bonified meat mixer, and it was certainly not worth the ~$250 price they get for them. Not for my small batch ways, and being able to multi-task the KA for two steps. Grinding and Mixing.
This is Disco's web page about making his Snack Sticks. And it has pictures of his use of his KA mixer for the process.

So You have to decide for yourself. I'm old and retired, I have more time than much else, so I can spend a lot of time playing
gently with the KA.
If I was going process animals, NO, the KA would not be the tool for the job.
But for an Old Fart (Me) that wants to make some Slim Jim sort of snack stix...
Oh yeah, it's good.
And before my casings even got here, I decided to order a stuffer. The KA can, in a marginal way, stuff the casings. But not really great at it. So after watching many video's of Snack Stick making, I could justify a stuffer.
napas posted about how he only uses a 5 pound stuffer now because it can do small to large stuffing very well. So bigger isn't always better. Forcing meat mixture through a smaller tube requires a bit of Hydraulics. A smaller stuffer offers that.
As long as one is willing to take the time, and not try and force things, smaller ways can work fine.
I could justify a couple of hundred bucks in my mind to make some tasty stuff.
But
no way any giant grinders, 44 pound mixers, or 30+ pound electric stuffers. I could buy a case of Slim Jim's for that cost.

Maybe a pallet full.
