What can I say? The documentation is more than thorough with plenty of working examples, I encountered no bugs, while a bit complex it can be customized to fit in almost any scenario imaginable, the quality of the product was excellent and and I was surprised it worked so well.
I can't say anything about support and you know why? I didn't need to use it, so maybe that says something about the quality of Justified Image Grid.
