Everything from the map option and below is asking me to upgrade to premium to unlock it. I don't even know how the captcha system works and I'm supposed to upgrade to find out that it may be weak? I would much prefer a nag screen on the contact page. At least that way I could see the power of the system.
The current method, I got up to four fields created before finding out that the product was a limited demo. Which again, that should be spelled out clearly for users on the download page.
Only the first 6 options are free. The map and the 7 other features shown in the video are not free.
Sorry for my rant, I'll just move on to something else.
