What do you like best?
I love the flexibility in modules and the ability to completely customize the look and feel. I also find it very valuable that you can manage all aspects of your event in one place, so all of the data is connected. It makes it so much easier to manage changes and communicate with attendees.
What do you dislike?
Advanced HTML/CSS knowledge is needed to really sufficiently design the event shell. Not all teams might have this resource available to them, so they have to spend additional dollars on contractors or agencies to help in the build. Once you get past this hurdle though, you can easily reuse past events to leverage code that was used before, so that is a plus.
Recommendations to others considering the product
Loop in your marketing ops and web/design teams when discussing implementation and execution to make sure that all necessary parties are engaged. This will streamline the rollout, maximize the integration and tracking capability, and will ensure that nothing is missed on the front end that will have to be considered later (like integrations with your MAP, tracking, SSO, etc.)
What business problems are you solving with the product? What benefits have you realized?
Certain allows me to keep everything in one place, to streamline my event management and automate so many event processes, from registration to session submissions, to networking event RSVPs, to surveys.
