Query: Only good as a nice-looking paper weight

The lamp looks very lovely. Unfortunately, it has a fatal flaw. The knob assembly that adjusts the angle of the lamp is not only made of a soft steel, but the screw is also of a very small diameter. The obvious result: When you attempt to tighten the lamp (even ever-so-lightly), the threads immediately strip-out. Result: The lamp is now a paper weight. This was such an obvious flaw, the designer must of been on some heavy medication to have missed it.
