It is very easy to use, I don't have any dislikes about it so far! The UI can be improved but overall this product has been great for us as we were using several different products previously that just weren’t working well together or kept track of who was attending events better than our previous solution which had an awful interface.
We are able now in one place easily see all details such tickets sold etc., links shared with attendees along their journey through event experience from Registration until after they leave (wherever possible).
