On the upside a rare gem of a feature was the ability to send two e-mails upon form submission, one to admin and one to user. It also allows for file to be attached to user e-mail. This is what I needed because I wanted one of my forms to send the customer a coupon (pdf attached to e-mail) after they "registered" for it.
It also acts as a front-man for their many other useful components. These apps all integrate very tightly, but they have a little bit of a ridiculous price tag IMHO.
Their support is very good but their documentation leaves a bit to be desired. My main complaint is PRICE, but I still give this component a 5.
BEST PART -- I had a problem with JCE when using this, I contacted the developer, he fixed it within 24 hours, just because i asked! You can't get this kind of support on Joomla extensions, this component is invaluable!
