I just used mine ( kitchen aid brand) today for homemade pizzas. Not having any data to compare with other grain mills, it works. It is slow for a fine grind. Very slow. So have time. It’s best for grinding small batch of what you need rather than a weeks worth. I will say, my pizza was amazing with fresh ground grains so if it’s the most affordable thing you can get, it does work. It is easy to attach. Another con would be the location of the flour falling. You can’t fit a bowl under there without it leaning on the base and having to prop the bowl up. But minor inconvenience.
