I read the reviews on this before purchasing it and it still was not what I expected. It appears to be similar to a laser light show when it is actually more of a colored strobe light. The lights flash to the beat of the music. It was very easy to hook up and can be used with pretty much any audio device. The lights are not very bright & look best when it is close to a wall or ceiling. I purchased this as a gift for someone who is mentally handicapped. I am now returning it, because I don't feel it is a suitable gift for someone who is prone to seizures.
