It is very easy to use and has all the functionality you need to manage an event. The customer service is also great! At this time there was nothing I disliked about Optimo. They have some really cool features that are not available at other companies. I would highly recommend doing market research before selecting another vendor. We needed a system that had so many different modules, they made it simple to choose what we wanted. This helped us with our budget as well since we could see exactly how much each module cost.
