[EX Q]: I'm not going to bother commenting on the content of this DVD, because even I feel it is an insult with all the errors and factual mistakes. First the most annoying error -- he has a group sitting in one room talking about the Holocaust without noting that almost every person who ever worked for or was persecuted by Nazis was Jewish, making no distinctions at all: they were all Jews.
[EX A]: Bad review

[EX Q]: Good book but I was hoping for a more detailed discussion about his experiences in the war. That being said, it does have some good info. On his early life and how he became so interested in military history which led him to write this book. Also lots of personal stories from World War II.
[EX A]: Good Review

[EX Q]: I have ordered these bulbs and been happy with the brightness of light. However, at first they burn brighter than expected. Now that my plants are about 3 years old and most don't grow well with just this type bulb, it seems dimmer on a few of them. Not sure if it's me or not, but we were replacing 40 watt lights - so for now, we may keep them as back up bulbs. Will switch to other LED bulbs, hope others help. 
 Rating: 4.
