I love how easy it was to set up my event for free! The only thing we had issues with when using this service were some graphics not loading correctly in our posts (we are an ecommerce site). We did have one issue where someone would signup as many times as they wanted but their profile never updated once showing them being signed into multiple devices at different time periods throughout events. That’s why we switched over to Eventbrite which has been so much better!! It's super affordable too and there aren't any surprises like having to pay extra fees if things go wrong. Nothing really stands out about thunder claps other than ease of use/cost effectiveness and their customer support team is great. Our biggest problem solving challenge now comes down to figuring out what content should get posted next since everything gets published automatically within minutes after signing up!
