Just installed it on a live site and used some of the functionality. I needed it for a basic calendar and event listing and it did the trick. There's so many other things it can do.

I wanted to add the sidebar calendar widget in Elementor, but didn't have an option for that. I contacted support and they promptly told me how to quickly adjust with CSS. Definitely great support.

Few things that could use improvement:
1. Knowledgebase search on their site includes topics on all of their products. If it could show topics based on the current product it would be easier to find answers.
2. Add a style manager (see how formidable forms does it) to allow us to individually style elements.
3. Page builder styles could use more options.

They have a strong roadmap - I'm looking forward to seeing the plugin evolve over time.

A strong 5 tacos in my eyes. If you're an agency or build many event based websites, Tier 3 is a great deal. Get it!
