All I can say is that it is always a pleasure when youbuy something and it works just as it says. This component is well-worth the money. You do need the JEvents calendar component installed for the whole system to work. The process is 1) input an event into the calendar, 2) you go into DT Register to mark the event as one users can register for and the details. Users register, pay for registration, you get an email, they get an email, you can email all registrants, etc. A lot of thought went into this component. I installed it for a client who has manay community events held at their location and they are very happy with it. I am too.
