I bought some of these for a bathroom -- and won't be using them. The screw and knob are packaged together (all the other pulls/knobs I ordered had the screw in a separate compartment so that the knobs didn't get scratched. All but a couple knobs have scuffs/scratches on them -- so simple to avoid if they'd only make the effort. My other fault with them is a "hollow" back side, so when you grab the pull, you can tell it's just a thin piece of metal shell, rather than a solid piece of metal.
The knobs look fine. They had similar ones at Walmart. However, they did not have enough for the job. You were able to ship the right amount but it took a little too long to be considered prompt. (~10 days)
