It is very helpful product. Very good size for larger vehicles. The downside is that it is held on by closing the doors on it, so it can take a few tries to get it snug. Design wise, it might be better if the straps had a latch on them to be able to secure it from inside the car better. But, if it is snow or freezing rain and not too much wind, then it has worked well. Overall happy with the product.
