The unmatched support.
I was looking for days for a slideshow that featured youtube videos. This one was the closest thing that did that. Still, not exactly what i was looking for. I contacted the support, with the little hope they could do something about it.
Surprisingly, within 15 minutes they told me that they would add that feature witin 24 hours. And they kept their promise! Further more, once they did that, i asked for even more slight modifications, and they keep answering my requests!
Worth every cent... Highly recommended.
