I adore this extension! I can use RSForm! Pro to create a form and it always works! I like how fast it is to create a simple form. I also like how everything is customizable. If I want to put forth the effort to make a form look a certain way, or make an email form result look smashing, the html coding is completely accessible and editable.I noticed some users have posted that it takes a long time to set up a form in this program. It takes a long time to set up a form (and form result emails) if you are very particular about what the final layout looks like. But honey, trust me - it takes soooooo much longer to get the same results building it all from scratch!
I use RSForm! Pro on my own business site and for client sites, too. The ability (through plugins) to put a form in articles is super-useful. I am very happy with this product and feel it is a great price value.
