Usually support is not free for none commercial extensions. I am not much experienced in IT. I am only a web designer. I got a problem with submitting files, which i couldn't found the reason. i made a call to mad4media and got instant support for free. if i could vote more than 5 Stars i would.
No doubt, the component is brilliant. The creation of forms is very easy.
Additionally this great support makes this product to my favourite form component.
