Just now I received the product and it is different from the pictures. I ordered this particular one because I noticed that some people who have issues with this type of product have complained about the product having a silver zinc finish and no grooves on the socket. Unfortunately the product I received is a silver zinc product. Coating.Hay, this product may still work. But the screw they used is of low quality. It may not be visible, but part of the top rosette is grooved and part is not. bad quality control.
