As far as UI goes, it is a bit awkward. Much like Office one. Also, it is not intuitive how to create a web site. I found Emtpy web site under Site from template option. However, this is just a small bump up the road. The fact that there are so many usable features like site report and easy database management and possibility of importing projects like WordPress and Drupal just proves that this is a serious start-up product. And on top of it it is free (yes, like beer).

Anyway… more info can be located on their official website. I suggest you give it a go.
