The product is multiply limited in its "demo" form to a ridiculous degree. It can't print without its logo on every page, it interrupts you to ask you to pay, it only allows you to edit 20 forms, etc. In my experience, a publisher this suspicious is not a good sign. Also, much of its functionality IS in the newer version f Preview -- as it should be. The PDF format was envisioned as a public, open standard. Finally, I hit several bugs in five minutes -- problems with fonts, an odd behavior with form fields and so on. I would be more sympathetic if the developer's price were lower and the attitude more positive, but I say look elsewhere.
