I sifted this product through three screens. I had very little waste in the last screen. I like this product, and would order again when I need more.
The quality is excellent. Dave called me about my concerns and explained the delay. They were crushing a new batch. I should have contacted him first. He is a really nice guy and sincerely wishes to satisfy his customers. The product is exactly what I wanted and very clean. As prove of my total satisfaction I plan on ordering more from these folks in the near future.
