Disappointed twice.  Side metal is loose.  I am also disappointed in this item because the colors are not deep and rich, like in the photo.  Far too much white light gets through and washes out the blue and green.   I will try to glue the metal to the glass rather than incur the cost of sending it back.  This  should not happen.  This makes me wonder what will happen when I hang it up...I do not see a happy future for this piece of glass.   Where is quality control!1
