I've used a few different extensions for creating forms on a Joomla! website, but honestly none compare to this one. After installation I didn't have any trouble creating my first custom form, and I love all the choice it gives you. Effortless forms that are created to fit in with the rest of your Joomla! template. I love it!
I wouldn't recommend anything else for anyone looking for a form extension. This one beats the others hands down!
