Love the look these added to my kitchen!  They are sleek, yet rustic looking with the antique finish.  Very sturdy!  And very easy to install. My husband and I were worried that over time, the knobs would start to spin and with them being square, we were worried it would be hard to manager over time if they began to spin.  So we added a little smear of Gorilla Glue to each screw before we screwed on the know, and I'm happy to report that they are rock solid.  They were perfect for the modern farmhouse look I was trying to achieve.
