Have installed it for several months now and it works nicely. The unusual design of covered grids is nice look and yet drawing in air thru the slim rectangular slot doe not increase noise nor decrease efficient air evacuation. I like it better than my $400plus Zephyr  I have in another home. One silly downside is that instructions are generic and did not actually cover my unit to reset time. Took a while to figure that out.
