Not really that good..
They look nice, but on closer inspection there were different types of friction rings under the adjusting knobs on 2 out of 5 tuners. This resulted in some tuners being quite heavy to turn. Two of those rings were ordinary plain metal wich caused too much friction.
So i changed those.
The hex screws for adjusting octave are not easy to acces once the strings are on, wich could be better. Other than that the tuners hold really well, so in their basic function they are ok. Next time however i wont buy single bridges, but a one piece headless bridge.
