I used this product and it was a good experience. With it I received more features than I would expect. In my case for a big website, the unliminted categories and unlimited events where very handy. You can customize most of it as you wish, this extension is very flexible. It is also easy to use and install - it takes you just couple of clicks. At some point I needed a bit of support and Eventsnova quick support. In the end I obtained all I needed for this web-page.
Thank you for your good product guys!
