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.

Review: Horrible film that should be avoided by all, exept maybe 10-14yr old boys. This film is actually worse than the second installation in the Transformers trilogy. I'm a fan of the first Transformers film & also the 1980's cartoon along with sci-fi films in general, but even for me & my easy-going taste in films, these two sequels are absolute pieces of rubbish.The Blu ray quality is fine though, crisp visuals with a strong TrueHD track, unlike the first film's release on Blu ray.

Review: The book presents a historical and political account of the middle east from 1922-1984. The book was originally written in 1968, then revised in 1976 and 1985. During the process of revision, Khouri, appearantly, did not make many changes in the original text, a fact that leaves much of the book outdated. Khouri's account takes a strong anti Israeli and pro Arab stance. For example, he chooses to downplay the Palestinian terrorist attacks during the 1970s and mentions such attacks as the attack on the Israeli athletes in Munich and the attack of the Marine base in Beirut with no detail. His study is based very closely on UN records and ignores the reality of the Middle East.
