I got mine over the weekend and so far I think its worth having for anyone interested in chameleons (although I'm not sure why anyone interested in chameleons wouldn't want any book related to them, even if it wasn't a particularly good one). I haven't had a chance to read the text yet but there are a lot of really nice pictures and for the most part, those pictures are labeled correctly (I think I saw four throughout the book that were misidentified or their name misspelt). It is not a book on the captive side of chameleons, etc., but I think chameleon keepers would enjoy it as well. I'll be sure to give a review of the text once I've had time to read it as well.
