In my humble opinion, ten dollars for one lighting setting isn't a low price at all. (Check the readme file, that's all this product is.) I'm not one to disparage merchants, nor do I mean to in this case, but I don't see how one little ol'light setting could possible equal "instant realism." Does even one of those ad pictures look "realistic" to anyone? Perhaps it really is a beautifully complex light setting, but well, I'll just leave it at "hmmmmm" and be very happy with the many outstanding global lights I got at DAZ for a grand total of four bucks. Still, I'm also interested to hear from any satisfied customers.
