    It works as it should.
    Color: Gravel Black
    It's what I was looking for. I cut the small foam stickers to keep it from moving around on counter into pieces & put the on the bottom works well. It did chance color? like white stained?

    Perfect
    Size: 16 Inch
    Exactly what I ordered, took just a few minutes to assemble and mount the legs. Love that the bottoms can be manipulated to give a balanced stance.
