As the publishers description says “You'll find that you'll be creating great looking Web sites almost instantly with virtually no learning curve. It offers the kind of power you would find in the leading commercial products. It's visual editor is actually powered by Microsoft Internet Explorer, so you can always be certain that you are seeing exactly what you will get when your Web site is uploaded to your server.”
The reviews I read are mostly good. Looks like it works great for simple sites and a good way to learn HTML, but professional designers using lots of the tricks of the trade do not find it useful. Of course I would think they would be sticking to Expression Web or Dreamweaver anyway!
Give it a try.
