I'd say this is a really nice piece of software. It works well and everything, however, it's 100% useless. Now, don't misunderstand me, I use things like this every so often and I do find them useful. However, this one charges you money for what various free programs do, and for a lot cheaper.
Screenshot Plus for instance can take a screen shot of just an icon. It's free. There are various plugins for Photoshop that can import icon data, including it's various states.
As a piece of software this is indeed nice, but I cannot justify paying $25 for it, not when there are so many other programs that you can get that are more flexible and cost you nothing.
