X-Mod Pro for databases is Powerful.. Fact.. every time I think "How will I do that", I just read the manual and a ready made solution usually exists. Also you must learn how to use XMod, XMod scripting is not that intuitive and has an initial learning curve but once mastered it has a superb and simple flow to it which allows you to build just about anything..A product worthy of full ratings.
My hosting is very restrictive and initially the module was unable to run, I was offered either a full refund or the new version in a few weeks time, it was worth the wait and the latest module runs beautifully and Evotiva are extremely professional and highly recommended.
A truly brilliant little module.. it took us 15 minutes to get exactly what we wanted without having to learn flash.. the only constraint now is our imagination
