Just be careful putting them on. It's easy to drop them on your tile floor and they chip easily. Best to put down a folded towel first. They came with extra screws that can be used in different lenghts. I'm impressed.
Looks great in my kitchen, I used them only for the drawers when the old knobs ran out and couldn't be replaced. I have cherry cabinets and cherry knobs, and these brighten up the drawers substantially -- kitchen walls are yellow and red, so this is an awesome match. Great quality, nice and sturdy, bright and pretty.
