It has helped us tremendously in taking a really complex business challenge and given us the only tool flexible enough to handle all of our requirements without building an even more complex backend solution from scratch.
Yes, building a plussed up form simple is super fast and easy. But the ability to layer in custom logic, call external scripts, and manipulate the presentation in response to the user with an insanely stable CMS tool is why this is such a great plugin.
On top of that, their support is awesome, and their attention to details and speed in delivering bug fixes are rare in the third party plugin world.
Thanks to Mark and his team!
