At the time of this review, this extension is one of a few options available with features. Don't be surprised when you get excellent support. I had a conflict with K2, these guys made it work in short order.
This is pretty mature software and not to hard on the eyes for common Joomla user. It really fits well serving the simple need to offer event booking, and outshines other extensions I tested A+. Now for some minor layout tweaks.
