this is one of the best extensions i have used in joomla! installation was breezy. it is very easy to use, each option is labeled well and there are sections for different types of settings. i have not needed support for it yet, but looking at the b2j forums it seems that issues are addressed promptly. the custom form options work great and offer a wide possibility of uses. the email that gets sent is well formatted. for a simple yet customizable contact form i have not found better.
