I only bought this item because I lost my first one. I have used it daily for over 10 years. It is evident that the black coating was almost completely worn away, but the bushing was not deformed or defective in the slightest. I can honestly say that this particular frame and its 12mm counterpart are two of the best frames I have ever owned. All of the sockets that I have replaced with GN sockets have been of better quality to begin with and over the years have performed better than the ones they replaced.
