We put one in this spring. Before and after, we used streamers to see how even the air was front to rear. The improvement was dramatic. Without the deflector, a high velocity air jet blasts upward at the front of the sieve and nearly no air goes out the rear of the sieve. With the deflector, the air flow was nearly perfect at a full range of fan speeds. We'll find out how much it really helps in a couple weeks cutting wheat, but I expect it to be well worth the money.
