I bought these as an upgrade to a Harley Benton TE-52 project (pictured). Easy fit and worked great to improve the intonation. Not sure if they improved sustain or not, but they certainly look more vintage than the chrome ones that came with the guitar.As for the lefty tip, I couldn't find lefty saddles, so I bought two sets of righty saddles and selected the ones I needed (which are opposite the righty ones, of course). At the low price, it was well worth it.
