This book was the worst one I have ever read. It should be required reading for anybody in politics. Do not support this trash book. He calls people who don't agree with him liars and racists. That's just gross. If we really care about other people, why are there lies that would take away from people's rights. He's the definition of a politician. The only person he has is himself to blame if he's so stupid to believe these stories. He seems like an intelligent, kind man.

I am giving this fan 2 stars only because my previous fan--another brand with no "swivel"--lasted about 5 yrs.

These look good and came pretty quick. However:1. The screen is NOT anti-glare. It has a small reflective area right in it's center. That's a nice touch.2. They are made of fairly thin plastic that seems to bend easily.3. When I put the first cover on it almost bent backwards because of all that weight. Had my friend help me install them thinking he could be more careful, but guess what, they don't work if you have any force.
