I utikise for 3 months. I try Vestax VCI 300. DJ for 15 years this product is very pro, I use same club with 4 other plates (cd and vinyl records) The advantage is that Vestax has a sound card integration, it is robust and I Jamis have been no crash. As for the knobs feel free to address them at your convenience by adding a small piece of cardboard under the crossfader (chut!!) The jogs are adjustable via a small screw. I regularly receive great DJ in my club and frankly they are all even at epates.Cette platinum should experiment with virtual DJ pro (of course) The fact that you can connect to two other devices to choose from vinyl records, cds and it to act as a mixer. It runs very well on PC because everyone did not have the means to move a MAC, given the quality and the price I would do without a doubt purchase.
