We bought this to go to Florida from New York since we needed the extra room for 2 dogs in our SUV. When I received it I kind of questioned the durability and weather it would stay put on our roof. We do not have roof rails to tie it to( which is why we could not buy the fiberglass unit) so had to go through the car to secure it. I have to say that it performed beautifully with no movement. Just make sure you secure it well with the straps and check it every time you stop to make sure it is still secure. I would also highly recommend the pad that goes under the bag which keeps it from skidding or moving. I drive at 75 to 80 mph on the Interstate and having a sunroof also helps so you can visually see how it rides. It was excellent. So far we have traveled over 2400 miles with no incident. Good purchase
