Good base, lots of customizing options, great service!

This plugin is very well made. It uses the core elements of WordPress for editing the events.
I like the idea of 1 production, with more events (dates of shows). Better than most eventcalendars that only dulicate the whole content for each same event on another date.
Due to the core elements this plugin can easily be extended with other plugins. I used Duplicate Post (copy productions and events) and Advanced Custom Fields (to add some more fields to the events).

If there’s a downside, than it’s that the output of the shortcode’s comes with some format and not ‘clean text’. But Jeroen was very kind and helpfull to solve this issue for my project.
The plugin is in active development that makes it trustworthy for the future.
