I've been using it for about 5years (in strip clubs) its pretty useful but I just recently got the VCI-100se to try to break into DJing in the local dance clubs. The mapping is a disconcerting enough that I'm plotting on getting Traktor Pro and keeping Virtual for video mixing only. Maybe it's just gettting the mapping right or something but Virtual Pro Full is great for what I'm doing currently...on of the other house Djs uses Serato but he was working dance clubs before this; never needed to swap software.
