The Reviews

The SportRack Aero XL Roof Box was reviewed by 80 different customers. Overall the reviews were very positive. The product received 4 and a half stars out of a possible 5. Reviewers liked that it was very easy to mount on their cross bar. It “feels sturdy” was one reviewers comment. No rattling or wind noise is heard inside your vehicle. Most people report this at speeds higher than 65 MPH.

A lot of reviewers liked the low price. For the space that you receive and the comfort gained inside the vehicle, it can’t be beat. It really does offer a lot of space. If you have a very tall vehicle, it’s not that hard to access the box because it actually opens from the back, instead of the side. You can just stand on your rear bumper. It does not seem to affect gas mileage whatsoever. This is from a reviewer that had updated his already good review of the product.

You will definitely see the quality in the product when you first open the package. It can accommodate a lot of gear. The lid opens at a good angle and allows for easy packing. Your cargo will arrive in the condition that you had originally packed it in and it will keep things dry. One reviewer did mention to properly check the U-bolt nuts throughout your trip. He did note that the lock nuts have nylon in the threads, but with the force and vibration that occurs on the trip, there is a possibility that they will come loose.

One negative comment I saw had nothing to do with the product, but more with the company’s website. One reviewer had mentioned that he wanted to get more information on the product after ordering it, but after visiting the website, realized that it was nothing more than a giant interactive sales brochure.
