The build quality of this part is great, but do make sure it actually fits your guitar. With my Gretsch it just a bit too wide, pushing the tuner bushings to the sides. Some careful sanding with a Dremel resulted in a better fit. The result is ok and does help with string binding. If you are using this on a Gretsch too, do not forget to file the nut slots too after installation so they align again with the new string angle.
