I have been using Breezingforms with Joomla for many years and I am glad that it has now also arrived with WordPress. I gave 4 years ago in September 2009 my first review of Breezingforms and if you look at the title of my review you will notice that after 4 years we as a large commercial services provider are still very happy with Breezingforms. We have tried some competitive extensions but the versatility of the Easymode Interface as well as the Easy to use Quickmode version and ease of creating the most difficult multi-page forms and form applications for our clients with the extensive scripting library that comes with the package makes us a happy user of Breezingforms.
Our clients are able (after reviewing the instruction videos on the BF website and with some basic guidance from us) to create are able to make their own forms with the Quickmode interface themselves. The documentation is extensive and the support by Markus and his Team is first class.
Over the past years we have seen this extension grow into a real Content Construction Kit and with the current exciting addons being developed for/with BreezingForms we are convinced that this extension is worth every single penny of its subscriptions if you choose to go commercial.
