Relatively good construction. The height and width of the shelves comfortably fit most shoe sizes. Very positive that the width is adjustable and fits everywhere, but it is designed in such a way that it does not have a stopper for the width, and if you pull it too much, it simply separates into two parts. The only thing it has is a red line that warns not to increase the width further. Finally, because it is open, it requires caution to prevent the shoes from touching the wall and getting dirty.
