Product review (1 stars): Houston Storm Victims Still Suffering.
After visiting friends in Houston, I noticed they needed a new exterior louver, and ordered this as gift. I ordered a 6 inch size, but received one nearly 8.5 inches.  A waste to send it to them now.  Since it was not important for the seller/supplier to send the correct size, the people in Houston who should have had this product in hand by the time Harvey arrived, and needed it to keep out pests with rising water, will have to figure the problem out another way....!
