The box can be easily attached to the rack. The supplied, stable mounting elements are provided with slots so that they are likely to be suitable for almost any bike rack. Attached are sufficiently long screws with safety nuts that can not be solved itself. In addition, I have used a little larger, stainless washers, so that can tighten the screws tight. The box sits firmly and does not rattle. The castle is simple, but the lid can be closed well. When opened, the cover does indeed a somewhat unstable impression. However, the sealed box is stable and watertight. For the day trip of a person, the volume is sufficient. The box can be with a small strap for example, even a raincoat fix. I am very pleased with the box and would buy it again, especially since the price is cheap.
