I love the look of this knob and it functions well. They really are beautiful, in my vicotrian, oil rubbed bronze bathroom. I use it in my guest bathroom. I can only give it 4 stars because in three of the six knobs I bought, the porcelain knob has come off of the screw. I have had to glue the knobs onto the screws because the inside of the knob wore down and the knob can no longer hold the screw. They are expensive to buy and expensive to replace when they malfunction.
