The fit, finish and operation of this box is outstanding. The lid closes and locks without drama from either side, and it has the feature where you can't take your key out unless it is closed properly and locked. The attachment system to the bars is easy to use and robust enough. Some noise but not bad, and does not radically reduce gas mileage. Plus this same size box in the other brand is almost a foot longer, which I did not want. All in all, highly recommend!
