Query: Rooftop Cargo Bag

We bought this for a trip we took to Florida. It worked out great. It rained on us on our way home, and everything stayed dry. Easy to secure to the roof rack. I did notice a slight decrease in our gas mileage. It did create some wind noise, and we had to adjust the straps so they wouldn't flap against the roof so much. We definitely got our money's worth from this.UPDATE: One corner tore on our first trip -- didn't notice it until the second time we went to use it.
