I do not like similar type of plugins - I found them completely uninteresting for me. I do not know why should I use them and what they can do for me that I can't do myself already. I am still waiting for some ground shaking video demonstrating it and impressing me.
GUI is simple, maybe too simple for your hard earned money, and workflow is really fast. Ask yourself if you really need it. If yes, check demo and you will be probably happy with it. If fast workflow is what you are after then it will deliver.
