We bought this because it's a perfect match to some furniture already in the room. To use the knob on the closet doors, however, we had to find a longer screw and it wasn't easy. The screws provided are metric, and the big box stores don't carry them. Solved the problem with a little running around, and the room looks spectacular.
The knobs look great and work well, but the supplied screws were not long enough to go through the drawer fronts, so I had to buy my own screws. They were difficult to find since they were metric, but I did finally find some that worked. The supplied screws were perfect for the cabinet doors.
