These door knobs are perfect. I had the original crystal door knobs throughout my house from the 1920’s and none of them actually functioned since I bought the house. I wanted to go back with crystal knobs but the way they build them nowadays all I’ve read were reviews about the crystals becoming unglued and not having a set screw. After plenty of researching I found the best avenue for me was to get these satin knobs ( even though retrofitting the old internals for modern ones was a project in itself). I must say these brushed satin knobs look amazing ( especially on white doors). I changed all 6 knobs throughout my home to match and I am beyond happy, now no I just have to finish painting doors and hallway.. smh.
