Nice little grinder for the money. I bought it to grind my homemade chicken feed and it worked great. I have made two 100 lb. batches so far. Easy enough to assemble, the little rubber feet covers don't stay on that well but not a big deal.So far I have ground corn, millet, flax seed, whole oats, soybean meal, and sunflower seeds. The sunflower seeds were a little oily and the first batch I ground worked fine but when I ground the second batch I had the grinder closed down to far and it wanted to plug up so I just cleaned it out and opened up the grinder a little. It would be nice if the funnel held about twice as much feed, I also added a little 2.5 inch PVC pipe on the discharge spout to funnel the feed into a 32 gallon trash can. Overall pretty quiet and was easy to clean when I was done. Feed mixture looked great very excited about this machine and making high quality feed for the girls. .47 cents per lb compared to .67 cents to 1.09 for the cheap stuff at the store, found a Nutrient pack Azure to make sure they are getting all the vitamins also.
