It’s easy to use, you can insert your form in an article as well as in a module, it’s also easy to create a customize display.
And if you have any question (I don’t talk of issue as I never had any issues with this component), the friendly support is more than efficient, they answer quickly and are always willing to help you and find the best solution.
I recommend this component, it really worths its price.
Some may ask questions about paying or not a membership. For us it was the best solution, it was obvious as we had a very important project, the price of the membership worths it !
So why only 4 stars? Because I am too demanding and I expect to see future developments, including alphabetical ordering of the entries, my problem ;-)
