What is your opinion of this product?
Just great! I started dj ing in the mid 70's and this takes that era to a whole ne level. The vitual dj pro upgrade that I did Just made it that much better. I use to master 3 turntable mixes the old way. Now this way it is easier and better. Here is the big big plus for me: The audio tracks lay over each other in the mix. So, visually I can mix by site and know when a beats in the mix are going to be off. I am not glued to the headphones any more. With old disco and real drummers tempo varies now I can see it before the changes. Virtual dj pro and the N4 are made for each other.
