The ShengShou Metallic 3x3x3 M is a magnetic 3x3x3 speedcube from speedcubing brand ShengShou, it features a metallic/shiny looking coating which some people prefer the look of, the ShengShou one is slightly cheaper than the Cyclone Boys alternative but does not perform quite as well. I suspect most people are not looking for the best performing one though, they may just want a metallic 3x3x3 that at least performs ok.
