I liked this component because it had all the features I had been waiting for in a Registration component, however I am disappointed that the Community Builder integration does not work as advertised. I have contacted the developers about this but still no response. I believe that if I have to pay for a component (over $100) it needs to work as advertised. The part about integrating with CB needs to be taken off the site until it actually exists otherwise that is known as "false advertising".
Community Builder field population integration is now working since version 2.5
