I'm building a partscaster and I tried saving in areas where I thought the quality of the products would not matter that much for the overall feel of the guitar. I expected a poor quality item, but I got something that could easily be on a Squier Classic Vibe, a PRS SE or something similar. It is exactly what is advertised. I have not tested them with strings yet(to see if they pop string ends or something), but given the fact that you use these in string through configuration rarely the ferrules have anything to do wtih string breakage.
Good item overall! All Harley Benton hardware exceeded my expectations.
