I only use two of the tricks from the CD, but it worth it. And I'm not a DJ. All the tricks don't
need black background. I use the colourchange of the CD and the vanishing CD. I needed it for a
specific routine to a challenge show on TV and I got what I needed and got on national TV, so I'm
happy. It looks great. To the vanishing CD I added some glimmer, so it appears as it turns into
glimmer.
I give it 5 because it's a strong effect and nobody else have thought of it.
Most
of the tricks are for stage but the colourchanging can be done closeup and looks great!
