Major design flaw - including the replacement. Does not stay upright as pictured.

Extremely disappointing. I have no idea why there are positive reviews for this. I ordered this due to the light features (which I enjoy) and also because it looks very adjustable. The issue is that it sags under its own weight. It collapses into itself. There is no way to tighten it. Gets two stars because customer service was excellent - they shipped me out a replacement right away. However, the replacement shows the same exact problem. It's just a design flaw. It can never look as it does in the picture. Now I have two useless lamps.
