Pros: Easy to install, form and field creation for a simple form was not to complicated, prebuilt examples were a plus, forms look good on the site.
Cons: In admin, About tab, it doesn't tell me what version I have. I thought the instructions on how to use were not clear. While I got some explanation using a ticket submission, I still had a problem figuring out how to implement a change. I believe this is due to the language barrier. Per this web site (JED), There had been no updates or improvements to the extension since the current version was released. Not a good thing.
Summary: The saying "You get what you pay for" applies here. It's a good extension for the money. It's easy to implement but don't expect any version upgrades in the near future.
