It's nice. I actually bought it because i don't consider myself in any way to be a mastering engineer, and its useful to get pretty decent results without having to pay a professional mastering engineer. Of course if i need mastering for a specific track that option is always there.
The best thing about it is it comes with a free mastering guide which teaches you how to use it. I've looked at about the 1st half of it and it's very easy to follow, just wish i had more time to finish going through it.
