“As advertised really. Easy to fit and adjust. Very low wind noise (but somewhat audible) at 70mph on the motorway when the box was on. As they are easy to fit/remove, I have not driven with them without the box. Very happy with this purchase. I originally wanted the Thule bars, but after speaking to team I decided to go for these as they were significantly cheaper and they were compatible out of the box with the box I purchased (didnt require removing any rubber like the Thules).”
