Compatibility with Blaze u0026amp; Special Edition,comes with 2 pins.The pin holes were in the correct locations and depth,as a result the band felt as secure u0026amp; fit as it did in the original frame.nThe frame/housing is extruded,high-density,strong plastic over an internal metal (very thin) rigid frame around the insertion point for the Blaze core.nMatte finished and look similar to the original frame.It looks fabulous, really gives this u0026#39;sportyu0026#39; product a touch of class.Great for professional environment、dress up occasions and much classier.nAll of the buttons feel solid、firm, donu0026#39;t make spring noise when pressed, and required a light depression of the button to cause the Fitbit blaze to respond.nThe new frame is much tighter and gives the desired impression that the Fitbit, frame, and band are all of a piece; not separate items popped together but one solid device.n
