I always read the reviews before using an extension but rarely leave one myself. In this case I felt compelled to write a review because the support from this developer is first class. I have been using the Event Booking component on a Joomla 1.5 site and having built a new site on the Joomla 2.5 platform needed to migrate the data form the J1.5 site to the new one. I had some trouble doing this myself and after contacting Tuan via the support desk, he promptly responded. A couple of emails later I now have a fully functioning J2.5 site with all of the event data from the old site successfully migrated.
A great component and an even greater developer!
