The first knob that I unwrapped had a bare spot right on the front of the knob, so it is unusable. When I opened the next package and tried to install one of the knobs on my cupboard it wouldn't tighten enough to fit securely on the door. Either the screws are too long or they didn't bore out the hole deep enough. Either way, I am going to either have to cut every single screw or buy enough washers to fill in the gap so that the knobs fit tightly. Would not buy again.
