Pretty decent for the cost, these are are basically the CDJ 2000's stripped down with slightly cheaper feel but v similar software at a third of the price. And no CD's. The only function I can't find is the attack and fade on a stop.
The mixer is quite irritating, underpowered Aux, and the nearly useless effects panel that can't be assigned to a chanel. Also phono or line... No inbetween for a second line... It is limited, but does the job enough.
