There are perfect for our roof deck.  We wanted something to add some greenery and foliage outside of a large window leading up to the roof. They are a little shorter than I would like, but honestly they work perfectly. Easy to assemble and love that there are three individual containers that are easy to lift out and move around.  Easy to change your mind about where you want different things.  I think I will order another set for a balcony off our living room to have a kitchen garden.  Note the black is not entirely black and I really like that.  Has a very expensive look for a reasonable price.  Don't hesitate.
