I like that it's easy to use, has great customer service/support if needed or requested (which was never), can be used for multiple events at once with ease as well! It does have some bugs here & there but nothing major so far in my experience using this software since 2014-ish when we first started utilizing their services then again now after they released version 4 which made life easier by leaps n' bounds!! We've been able t o keep our registrations up without having any issues from themβ¦
