Product review (1 stars): Hurricane Harvey not the only disappointment!
After visiting friends in Houston from another state, I noticed they needed a new exterior dryer louver, and ordered this as gift. I ordered an 8 inch size, but received one nearly 4 inches too big.  Completely useless to send it to them.  Since it was not important for the seller/supplier to send the correct size, I guess the people in Houston who should have had this product in hand by the time Harvey hit, will not be able to keep pests our of their home now!!!
