If you are looking for a flexible, reliable and well supported form-extension, you just found it. I tried all the other well known extensions and I am very pleased with this one. No hassle, very easy to set up and just for a few bucks.
I needed the support two times for some questions. I always got an answer within hours. This is just perfect service!
I am using this component now on all my clients sites. It saves me a lot of time.
