Just Perfect! Thank you Wayfair for delivering on time as promised and right before the first heat wave of the summer 2024 here in NYC! Easy assembly and works great! Very quiet too! We had to cut down one of the two window inserts, because it would not have fit in our basement window, but it really was not a big deal. The alternative would have been to use just the one of the two pieces and another smaller "filler "of a sort. Great purchase!
