I tested the trunk already difficult conditions, such as gravel roads, cobblestones and the like and am absolutely thrilled! He has so far withstood all except the slightly scratched the outer shell, but it is an absolutely great value for money and ultimately not super expensive competitors product. An extra star is there for the rolling capacity both in width tilted and standing on the narrow side! Amazed me the spaciousness of the case and the additional positive by a zipper available storage space!
