It's very well built, with tough materials and seams, plenty of spare room for clothing/shoes etc, and the legs have a strong spring mechanism that locks them recessed into the bag, but which with effort, can be snapped out, locking strongly into place. The omnidirectional wheels are a godsend for silky easy of flow in straightaway or turns. Highly recommended for anywhere, but in my case for long airport walks, and in parking lots.
