Personally I didn't like it, while it did a good enough job of the HDR I just didn't find the interface very "user friendly" it gave the impression of being thrown together, rather than a professional product.
I much prefere Photomatix, or Dynamic photo HDR, they suit "my" style of working better. Best bet is give it a try and see if it works for you, I think a lot depends on how you have shot the original images, and how much time your prepared to spend on the HDR process. Wayne
