PROBLEM: Review: There are plenty of tension rods out there. The _only_ advantage of the Umbra rods is that they look better. (Why other manufacturers haven't figured out the design part is anybody's guess.) The problem with the Umbra rods -- all of them -- is NO tension. I have tried these repeatedly.... Why? Because my local hardware store carries them, and they are readily available elsewhere, and I have opted for form over function. Every single Umbra rod I have used fails drastically. They simply cannot bear any weight. Or, to put it differently, they cannot exert enough force against the surfaces they extend out to for them to bear any load. Worse, the springs that are the key element in sustaining the tension tend to fail. When those springs fail, anything you have suspended by the rod will come down. If it's a lightweight drapery panel, you may be in luck. Otherwise, forget about it.

PROBLEM: Review: This book [stinks]. I read this book only, because I seen the preview for the movie. It jumps around from one thing to the next. John Keel is a nut, "the phone rang and nobody was there!" "That could only mean the time traveling space aliens, cause no human would be capable of calling my house and hanging up." "The CIA/FBI are out to get me" Please!!! Go see a shrink.
