Waited to review until I had processed several batches, totaling 19 kilo (42 pounds approx). Grinding Top Side and Bacon for Hamburger meat. Starting with Semi Frozen meat, Froze the Grinder itself and ran it through the grinder twice (2nd largest size holes, as recommended in owners guide). I bought the stainless steel version and it is well made and secure and snug fitting to my Classic Kitchen Aid Mixer (only a couple years old). It came with 2 of the 4 blade cutters and one two blade cutter. It works really well and was concerned as it was not the Kitchen Aid brand, but took a chance because it was stainless steel. I am really happy I did. This product is first class. This product works as intended, but it is suited for home use, not heavy commercial use. The weakness is the Kitchen Aid mixer itself, it gets very hot on big batches and will strain and slow the motor. On first grinds, had to stop mid-batch to let the motor cool and take care not to push too much product through. Super for home but recommend a commercial grinder for large amounts of meat on a daily basis. One suggestion that I might eventually need is replacement blades, I don't see them available anywhere.
