This product burns the steak to a crisp in 6 hours. The instruction states to dry for 1-2 days, rotating every 6 hours. I dried the steak for 2 hours and noticed that the beef was getting burnt in the bottom trays. Therefore, the trays were rotated in 2 hours, then 4 hours. At the end of the 6 hours, the beef in all of the trays were burnt to a crisp.
