I don't know. I ordered it 22 days before leaving for a long deployment in Europe in the Near East and it didn't arrive before I left. Since I am not home, and I wont't be home for another year, I can't make a determination. I was able to pick up another book on Joomla so I would have a reference while I was out of the country, trying to work on some projects, and IT was helpful. Anyway, if ti's it's there when I get home, I will let you know what I think.
