I use it for 8 months.

I already tried the cdj 400.

+: Size
Plug and Play
-: Plastic button, not practical (cue hot cue)
pitch while the 0.5 non-specific
no sound card
incomplete software (Virtuality screen)
you can not see the effect selected
decision not to move if the USB controller disconnects and you must restart the software

This product is very good to start as very simple to use. Very good Q / P
I will not repeat this choice because it is really to do this by hand at first. It still manages to make a good mix.
